The graphics driver must support this feature. Under the power plan that is configured, click Change plan settings , and then click Change advanced power settings. Expand Sleep , and then modify the sleep configuration settings as appropriate for your requirements. If Sleep does not appear on the Advanced Settings tab of the Power Options dialog box, the computer does not meet the requirements to support the sleep feature.
In this scenario, you may have to update the drivers or the devices on the computer.

Note If Windows Aero does not appear in the Color scheme list, the graphics adapter may not support Windows Aero, or you may have to update the graphics adapter drivers. Important We recommend that you do not turn off Internet Explorer Enhanced Security Configuration for a group for which that you are not a member. Note The graphics driver must support this feature. NetDMA should be automatically enabled if it is supported.
The network improvements in the operating system are intended to improve network throughput on servers by offloading some networking tasks to the network adapter's hardware.
This mostly applies to adapters that are running at 1Gbps and higher connection speeds and require that the network adapters and drivers that are being used implement the improvements. If the driver doesn't support the improvements, or if the driverhas a problem that is related to them, you may have to disable them manually. A newer driver for the network adapter may resolve any networking issues that are being experienced. Use the following information to check the network adapter settings and the OS settings for SNP settings.
Determine driver information in Windows Server and Windows Server R2 You can find the date and version of the network driver. To do this, follow these steps:. Click Device Manager in the navigation pane.
You should see something that resembles the following screen shot. Next, go to the website of the Driver Provider also on the Driver tab. Check for the latest version of the driver and see whether it is newer than the driver date that you found in the device properties. You may also find a solution in a FAQ or on a forum on the manufacture's site. If updating the network drivers doesn't work, you might want to try disabling the improved features and see whether the issue resolves.
Use this as a last resort or a troubleshooting step and not as the solution unless your network adapter was confirmed not to support the features in question. The improved networking features can be enabled or disabled in the operating system and also in the network adapter's advanced settings.
To see the settings for the operating system, use net shell command "netsh interface tcp show global" command as follows: You can check the following two other settings that affect TCPchimney offloading:.
If necessary, run this scenario in a dedicated maintenance window to avoid any problems. An increased workload that is caused by a trace or benchmark test can adversely affect the performance of your VM. This scenario runs a performance counter trace by using the counters that are specified in the RuleEngineConfig. It does so by using the counters that are found in the RuleEngineConfig. This scenario also includes performance diagnostics data. This scenario runs a special performance counter capture together with a network trace.
The following are some key SMB client share performance counters that are part of the capture:. When you run an advanced performance analysis, you select traces to run in parallel. Information about Windows VM, disks or storage pools configuration, performance counters, logs, and various traces are collected. It depends on the performance scenario you are using. The following table provides details:. Runs a rule-based engine in the background to collect data and diagnose ongoing performance issues.
For the benchmarking scenario or the "Advanced performance analysis" scenario that is configured to use Xperf or Diskspd, the tool might adversely affect the performance of the VM. These scenarios shouldn't be run in a live production environment. By default, the tool uses the temporary storage drive to collect data. If tracing stays enabled for a longer time, the amount of data that is collected might be relevant.
This can reduce the availability of space on the temporary disk, and can therefore affect any application that relies on this drive. You can also run it as a standalone tool.
Download PerfInsights. Unblock the PerfInsights. To do this, right-click the PerfInsights. In the General tab, select Unblock , and then select OK. This action ensures that the tool runs without any other security prompts.
Expand the compressed PerfInsights. Open Windows command prompt as an administrator, and then run PerfInsights. You can use the following example to run the advanced scenario with Xperf and Performance counter traces for 5 mins:.
