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. For comparison, the transmission time for packet transmissions over long distances is usually measured in milliseconds an order of magnitude larger. This tuning will not reduce the time a packet spends in transit. However, note that this is system and BIOS dependent, and some systems will provide higher performance if the operating system controls power management.
You can check and adjust your power management settings from Settings or by using the powercfg command. For more information, see Powercfg Command-Line Options. Besides, re-enabling write caching will improve Vista performance. The only downside of enhancing write caching is potential risk of data loss in case of power cuts. So, unless you are a laptop user and your battery is there to save you, be careful and backup everything.
Now you know how to speed up your computer running Vista operating system. For more performance tweaks try out a comprehensive system utility - Auslogics BoostSpeed. With this program you will be able to tune over hidden system settings to speed up your Vista's performance. Disclaimer: PC security and performance improvements will vary depending on the condition of your system and many other factors outside of the Company's control.

Preliminary studies have suggested that the strain is more infectious than the Delta variant which sparked the previous wave of infections, but there is also evidence that it is milder than its predecessors and those infected with Omicron are less likely to require hospitalisation.
In December, the hawkish signals by the US Federal Reserve induced market jitters ahead of its policy meeting on Dec , clouded by the possibility of an interest increase and a quicker tapering of its bond-buying programme. Nonetheless, the Federal Open Market Committee decided to double the speed of tapering but left the key interest rate unchanged.
However, across the Atlantic, the Bank of England emerged as the first major central bank to introduce a rate hike in the pandemic era, lifting its key rate to 0. Amir Imran Husain Safri.
