You might have a QoS feature on your wireless router or mesh Wi-Fi system. This would allow you to prioritize certain types of traffic: For example, you could ensure that all traffic to and from your work or gaming PC is high priority. Applications running on your computer can use the reserved bandwidth for high-priority network tasks.

They just have to tell Windows that certain traffic is high priority. Your download will take a bit longer, but there will always be a good chunk of bandwidth for a high-priority task—like streaming a video, perhaps.

This could actually make the network applications that you care about less responsive. If no program is using QoS, then all your bandwidth is available to non-QoS programs. Windows will still use just as much bandwidth for updates as it otherwise would, but those updates might now slow down your higher-priority network traffic.

There are other settings in Windows that give you power over this. For example, you can set a download bandwidth limit for Windows Update, or even tell Windows Update not to download updates automatically. Once someone writes a tip and posts it online, it takes off, and other people copy it from website to website.

Windows XP components such as Windows Update use BITS to download updates so only idle bandwidth is used to download updates and downloading can be resumed in case network connectivity is interrupted. BITS uses a queue to manage file transfers and downloads files on behalf of requesting applications asynchronously, i. The transfer will continue in the background as long as the network connection is there and the job owner is logged in.

If a network application begins to consume more bandwidth, BITS decreases its transfer rate to preserve the user’s interactive experience, except for Foreground priority downloads.

Windows XP has a Fax Console to manage incoming, outgoing and archived faxes and settings. The Fax Monitor only appears in the notification area when a fax transmission or reception is in progress. If manual reception of faxes is enabled, it appears upon an incoming fax call. It operates over IPv6. PNRP : This provides dynamic name publication and resolution of names to endpoints.

PNRP is a distributed name resolution protocol allowing Internet hosts to publish “peer names” and corresponding IPv6 addresses and optionally other information.

Other hosts can then resolve the peer name, retrieve the corresponding addresses and other information, and establish peer-to-peer connections. With PNRP, peer names are composed of an “authority” and a “qualifier”.

The authority is identified by a secure hash of an associated public key , or by a place-holder the number zero if the peer name is “unsecured”.

The qualifier is a string , allowing an authority to have different peer names for different services. If a peer name is secure, the PNRP name records are signed by the publishing authority, and can be verified using its public key. Unsecured peer names can be published by anybody, without possible verification. Multiple entities can publish the same peer name. For example, if a peer name is associated with a group, any group member can publish addresses for the peer name.

Peer names are published and resolved within a specified scope. The scope can be a local link, a site e. Each peer in the overlay network corresponds to a node in the graph. Nodes are resolved to addresses using PNRP. All the nodes in a graph share book-keeping information responsible for the functioning of the network as a whole. For example, in a distributed resource management network, which node has what resource needs to be shared.

Such information is shared as Records , which are flooded to all the peers in a graph. Each peer stores the Record to a local database. A Record consists of a header and a body. The body contains data specific to the application that is using the API; the header contains metadata to describe the data in the body as name-value pairs serialized using XML , in addition to author and version information.

It can also contain an index of the body data, for fast searching. A node can connect to other nodes directly as well, for communication that need not be shared with the entire Graph.

A Group can be shared by multiple applications, unlike a Graph. All Records exchanged are digitally signed. Peers must be invited into a Group. The invitation contains the GMC that enables it to join the group. Windows XP introduces a more simplified form of sharing files with local users in a multi-user environment and over the network called Simple File Sharing.

By checking the Make this folder private option in its Properties, local Administrators are also denied permissions to the My Documents folder. Simple File Sharing disables granular local and network sharing permissions. It shares the item with the Everyone group on the network with read only or write access, without asking for a password but forcing Guest user permissions.

This newer client works as a system service at the network-redirector level immediately above the file-system , allowing WebDAV shares to be assigned to a drive letter and used by any software, even through firewalls and NATs.

Applications can open remote files on HTTP servers, edit the file, and save the changes back to the file if the server allows. The WebDAV mini-redirector is known to have some limitations in authentication support. Although Windows XP did not ship with the following major Windows features out-of-the-box, these new features can be added to Windows XP by downloading these components which were incorporated in later versions of Windows.

Beginning with Windows XP SP2, the audio volume taper is stored in the registry for on-screen keyboard and remote control applications and can be customized by third parties, [] and Internet Explorer has improved Group Policy settings support beyond security settings.

There is IEEE For mass storage devices, Windows XP introduces hardware descriptors to distinguish between various storage types so that the operating system can set an appropriate default write caching policy. Device Manager provides a configuration setting whether to optimize devices for quick removal or for performance.

As mentioned in the above section , Windows XP includes improved support for FireWire cameras and audio video devices. Direct memory access over the bus from the host to the target allows kernel debugging over FireWire. It is intended to prevent an application or service from executing code from a non-executable memory region. This helps prevent certain exploits that store code via a buffer overflow , for example.

Software-enforced DEP does not protect from execution of code in data pages, but instead from another type of attack SEH overwrite. If DEP is enabled for all applications , users gain additional resistance against zero-day exploits. Therefore, DEP is not enforced for all applications by default in bit versions of Windows and is only turned on for critical system components.

Windows XP Service Pack 3 introduces additional NX APIs [] that allow software developers to enable NX hardware protection for their code, independent of system-wide compatibility enforcement settings. Developers can mark their applications as NX-compliant when built, which allows protection to be enforced when that application is installed and runs. This enables a higher percentage of NX-protected code in the software ecosystem on bit platforms, where the default system compatibility policy for NX is configured to protect only operating system components.

Like Internet Connection Sharing, the firewall has a location-aware policy, meaning it can be disabled in a corporate domain but enabled for a private home network. It has an option to disallow all exceptions which may be useful when connecting to a public network. The firewall can also be used as the edge firewall for ICS clients.

When the firewall blocks a program, it displays a notification. It supports port mapping and ICMP. Security log capabilities are included, which can record IP addresses and other data relating to connections originating from the home or office network or the Internet. It can record both dropped packets and successful connections. This can be used, for instance, to track every time a computer on the network connects to a website.

Windows Firewall also supports configuration through Group Policy. Windows Security Center provides users with the ability to view the status of computer security settings and services.

Windows Security Center also continually monitors these security settings, and informs the user via a pop-up notification balloon if there is a problem. The Windows Security Center consists of three major components: A control panel , a Windows Service , and an application programming interface that is provided by Windows Management Instrumentation.

The control panel divides the monitored security settings into categories, the headings of which are displayed with color-coded backgrounds. The current state of these settings is determined by the Windows service which starts automatically when the computer starts, and takes responsibility for continually monitoring the system for changes. The settings are made available to the system through a WMI provider. Anti-malware and firewall software vendors can register with the Security Center through the WMI provider.

Windows Update settings and status are also monitored and reported. From Wikipedia, the free encyclopedia. This article relies too much on references to primary sources.

We also recommend using ECN if you are enabling the CoDel scheduling algorithm to combat bufferbloat and reduce latency. Some EA multiplayer games that require a profile logon do not support ECN yet you will not be able to logon.

Note that if supported, ECN can reduce latency in some games with ECN-capable routers in the presence of packet loss dropped packets.

Receive Segment Coalescing RCS is able to collect packets that are received during the same interrupt cycle and put them together so that they can be more efficiently delivered to the network stack. While this reduces CPU utilization and improves thorughput, it can also have a negative impact on latency. That is why we recommend you disable it where latency is more important than throughput. Possible states: enabled, disabled, default. Default state: disabled Recommended: disabled for pure gaming latency, enabled for better throughput.

To enable using netsh:. Notes: Only supported by some network adapters. May need “Checksum Offload” enabled as well to work. Large Send Offload lets the network adapter hardware to complete data segmentation, rather than the OS. Theoretically, this feature may improve transmission performance, and reduce CPU load.

The problem with this setting is buggy implementation on many levels, including Network Adapter Drivers. Intel and Broadcom drivers are known to have this enabled by default, and may have many issues with it. In addition, in general any additional processing by the network adapter can introduce some latency which is exactly what we are trying to avoid when tweaking for gaming performance. This could be checked with “Task Monitor”. Otherwise, you can leave it enabled.

In general, any type of packet or memory coalescing can reduce CPU utilization also power consumption and increases throughput, as it allows the network adapter to combine multiple packets, however, coalescing can also have negative impact on latency, especially with more aggressive settings. That is why it should be either disabled, or used very conservatively for gaming.

This may increase network latency. TCP Offloading: TCP Offloads can improve throughput in general, however, they’ve been plagued by driver issues in the past, and, they also put more strain on the network adapter. For pure gaming and lowest possible latency, the only safe offload that should be left to the network adapter is “Checksum Offload”.

Disable Interrupt Moderation: If your Network Adapter supports this setting, it should be disabled for the lowest possible latency at the expense of a bit higher CPU utilization. For some of those settings specific to your OS, see our tweaking articles.

To disable at the network adapter, see our Network Adapter Optimization article. Most broadband users have some type of NAT router that sits between them and the internet. There are some settings that may help your router better prioritize gaming traffic and improve gaming experience. Enable upstream QoS in your router. It may be useful to enable upstream QoS at the router, if available, to prioritize the different types of traffic. Upstream QoS is important, because typically residential connections have much lower upstream cap, and when upstream bandwidth is all utilized, it can introduce some delay in the downstream traffic as well.

Note this is only recommended for newer routers, where the router has ample computing power to handle the QoS overhead. Use Open Source Firmware. Many NAT router models support open source firmware, such as dd-wrt, Tomato, etc.

It is a great feature to use, however there is a catch – it is only available when not using certain other incompatible features that need the Linux functionality like QoS. You’d have to pick which feature you prefer by testing. In some server operating systems Windows Server , the SystemResponsiveness may be set to , instead of 20 by default. This is by design, giving higher priority to background services over multimedia.

See also: MSDN ms Nagle’s algorithm is designed to allow several small packets to be combined together into a single, larger packet for more efficient transmissions. Keep in mind that disabling Nagle’s algorithm may also have some negative effect on file transfers. Nagle’s algorithm is enabled in Windows by default. To implement this tweak and disable Nagle’s algorithm, modify the following registry keys. Find the correct one with your IP address listed. For gaming performance, recommended is 1 disable.

For pure throughput and data streaming, you can experiment with small values over 2. Wifi performance may see a slight improvement with disabled TcpAckFrequency as well. Note you can also set this to 1 to reduce the nagle effect from the default of ms without disabling it. Note that only version 4 of the prorgam supports Windows 8 and newer and works with PowerShell cmdlets.

There program is available in our downloads section. More detailed information about all available options is provided in the TCP Optimizer documentation , answers to frequently asked questions are available in the Optimizer FAQ , and personalized help is available through our forums. Username: Password: forgot password? Home » Articles » Registry Tweaks. What about registry tweaks?

Nagle’s algorithm applies to TCP packets only. It was designed to buffer data small 1-byte keystrokes, for example until a full packet’s worth is collected before sending it out. Is there any tweaks to improve UDP?

Many games use TCP as well, disabling Nagling is well documented and tested for reducing latency in some games. Check the Gaming Tweaks article. If you use up all your bandwidth regardless of the protocol , you will experience delays and other congestion issues.

We can discuss this in more detail on the forums if you’d like. Thank you for the info, this info fixed one of the issues I had. Heuristics restricts autotuning if the connection type is “Public”, for security reasons. So if your connection is “Public” try the following: 1. If experiencing problems: 3. TcpTimedWaitDelay i wouldnt set this to 30 second why ,here is ms : The TcpTimedWaitDelay registry setting defaults to a value seconds, which represents 2 times the maximum segment lifetime of seconds or 4 minutes.

However, you can use this entry to customize the interval. Reducing the value of this entry allows TCP to release closed connections faster, providing more resources for new connections. However, if the value is too low, TCP might release connection resources before the connection is complete, requiring the server to use additional resources to re-establish the connection.

This registry setting can be set from 0 to seconds. The only downside of closing the connection is a very small overhead if it the need arises for it to be established again. And i know that if TCP is set to It will pretty much grab all the bandwidth and cause udp issue But if I set udp lower say 80 byte then the CPU will have a fitting caught.

Windows PowerShell The Windows PowerShell is a tool developed by Microsoft designed to replace and extend the functionality of the command prompt. To see current tcp parameters in netsh, use: netsh int tcp show global You will see something like the following: There are two extra settings in Windows 8. The possible settings are as follows: disabled: uses a fixed value for the tcp receive window.

Disable Windows Scaling heuristics Windows 8 as with Windows 7 has the ability to automatically change its own TCP Window auto-tuning behavior to a more conservative state regardless of any user settings.

To pick a single adapter and only modify its checksum offload state, find installed adapters using this cmdlet: Get-NetAdapter Receive-Side Scaling State RSS The receive-side scaling setting enables parallelized processing of received packets on multiple processors, while avoiding packet reordering.

Packet Coalescing This setting defines the grouping of network packets in general, to limit the number of receive interrupt and reduce the amount of required processing.
