This software is also available for download directly from Uhlik , as well as Citadel Industries. Note that this should only be needed pre-Service Pack 2, and a patched tcpip.

Note that if you're using the TCP Optimizer program, there is no need to apply any of those registry patches, as they modify the same parameters. You should really experiment with different settings and add them manually or using our TCP Optimizer program above rather than applying generic patches, however we've added them for simplicity, ease of installation and the many requests.

Please make sure you download the patch for your version of Windows, they are slightly different. Note: All patches are compressed and downloadable in "zip" format. This is an updated version of our original regstry patch, it's an. To install, extract the file first, then just right-click on the. You need to reboot for changes to take effect.

By default, when a DNS lookup fails due to temporary DNS problems , Windows still caches the unsuccessful DNS query, and in turn fails to connect to a host regardless of the fact that the DNS server might be able to handle your lookup seconds later. This patch fixes the problem by configuring the DNS client to continue sending queries to an unresponsive network. To install, save to your HD, unzip the.

Use the information in this topic to tune the performance network adapters for computers that are running Windows Server and later versions.

If your network adapters provide tuning options, you can use these options to optimize network throughput and resource usage. Turning on network adapter offload features is usually beneficial. However, the network adapter might not be powerful enough to handle the offload capabilities with high throughput. These technologies are deprecated in Windows Server , and might adversely affect server and networking performance.

In addition, these technologies might not be supported by Microsoft in the future. For example, consider a network adapter that has limited hardware resources.

In that case, enabling segmentation offload features might reduce the maximum sustainable throughput of the adapter. However, if the reduced throughput is acceptable, you should go ahead an enable the segmentation offload features. Some network adapters require you to enable offload features independently for the send and receive paths. RSS can improve web scalability and performance when there are fewer network adapters than logical processors on the server. When all the web traffic is going through the RSS-capable network adapters, the server can process incoming web requests from different connections simultaneously across different CPUs.

Before you start using RSS profiles, review the available profiles to understand when they are beneficial and how they apply to your network environment and hardware. For example, if you open Task Manager and review the logical processors on your server, and they seem to be underutilized for receive traffic, you can try increasing the number of RSS queues from the default of two to the maximum that your network adapter supports.

Your network adapter might have options to change the number of RSS queues as part of the driver. For network adapters that allow you to manually configure resources such as receive and send buffers, you should increase the allocated resources. Some network adapters set their receive buffers low to conserve allocated memory from the host. The low value results in dropped packets and decreased performance.

Therefore, for receive-intensive scenarios, we recommend that you increase the receive buffer value to the maximum. If a network adapter does not expose manual resource configuration, either it dynamically configures the resources, or the resources are set to a fixed value that cannot be changed. To control interrupt moderation, some network adapters expose different interrupt moderation levels, different buffer coalescing parameters sometimes separately for send and receive buffers , or both.

You should consider interrupt moderation for CPU-bound workloads. When using interrupt moderation, consider the trade-off between the host CPU savings and latency versus the increased host CPU savings because of more interrupts and less latency.

If the network adapter does not perform interrupt moderation, but it does expose buffer coalescing, you can improve performance by increasing the number of coalesced buffers to allow more buffers per send or receive. Many network adapters provide options to optimize operating system-induced latency.

Latency is the elapsed time between the network driver processing an incoming packet and the network driver sending the packet back. This time is usually measured in microseconds. Biden to send military medical teams to help hospitals.
