Windows Auto-Tuning is a feature introduced in Windows Vista and still in use on Windows 10. Windows Auto-Tuning was designed to automatically improve the performance for programs that receive TCP data over a network. Windows Auto-Tuning should be enabled and left alone unless you have a router, WI. Jika Anda adalah salah satu pemilik PC atau laptop yang menjalankan Windows 10 dan mengalami masalah pada kecepatan Internet yang di sebabkan pembaruan Windows 10, Anda perlu mencoba cara berikut ini untuk memecahkan masalah tersebut. Untuk mengelola fitur Window Auto Tuning, Anda bisa coba langkah-langkah berikut.
Applies to: Windows Server 2019, Windows Server 2016, Windows Server (Semi-Annual Channel)
Use the information in this topic to tune the performance network adapters for computers that are running Windows Server 2016 and later versions. If your network adapters provide tuning options, you can use these options to optimize network throughput and resource usage.
The correct tuning settings for your network adapters depend on the following variables:
The following sections describe some of your performance tuning options.
Enabling offload features
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.
Important
Do not use the offload features IPsec Task Offload or TCP Chimney Offload. These technologies are deprecated in Windows Server 2016, 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.
Note
Some network adapters require you to enable offload features independently for the send and receive paths.
Enabling receive-side scaling (RSS) for web servers
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.
Little snitch discount reddit. Important
Avoid using both non-RSS network adapters and RSS-capable network adapters on the same server. Because of the load distribution logic in RSS and Hypertext Transfer Protocol (HTTP), performance might be severely degraded if a non-RSS-capable network adapter accepts web traffic on a server that has one or more RSS-capable network adapters. In this circumstance, you should use RSS-capable network adapters or disable RSS on the network adapter properties Advanced Properties tab.
To determine whether a network adapter is RSS-capable, you can view the RSS information on the network adapter properties Advanced Properties Guitar pro 6 rse mac download. tab.
RSS Profiles and RSS Queues
The default RSS predefined profile is NUMAStatic, which differs from the default that the previous versions of Windows used. Precision tune auto care mn. 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.
Increasing network adapter resources
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.
Enabling interrupt moderation
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.
Performance tuning for low-latency packet processing
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.
Following are some performance tuning suggestions for microsecond-sensitive networks.
System management interrupts
Many hardware systems use System Management Interrupts (SMI) for a variety of maintenance functions, such as reporting error correction code (ECC) memory errors, maintaining legacy USB compatibility, controlling the fan, and managing BIOS-controlled power settings.
The SMI is the highest-priority interrupt on the system, and places the CPU in a management mode. This mode preempts all other activity while SMI runs an interrupt service routine, typically contained in BIOS. https://high-powersec540.weebly.com/download-game-guardian-560-apk.html.
Unfortunately, this behavior can result in latency spikes of 100 microseconds or more.
If you need to achieve the lowest latency, you should request a BIOS version from your hardware provider that reduces SMIs to the lowest degree possible. These BIOS versions are frequently referred to as 'low latency BIOS' or 'SMI free BIOS.' In some cases, it is not possible for a hardware platform to eliminate SMI activity altogether because it is used to control essential functions (for example, cooling fans).
Note
The operating system cannot control SMIs because the logical processor is running in a special maintenance mode, which prevents operating system intervention.
Performance tuning TCP
You can use the following items to tune TCP performance.
TCP receive window autotuning
In Windows Vista, Windows Server 2008, and later versions of Windows, the Windows network stack uses a feature that is named TCP receive window autotuning level to negotiate the TCP receive window size. This feature can negotiate a defined receive window size for every TCP communication during the TCP Handshake.
In earlier versions of Windows, the Windows network stack used a fixed-size receive window (65,535 bytes) that limited the overall potential throughput for connections. The total achievable throughput of TCP connections could limit network usage scenarios. TCP receive window autotuning enables these scenarios to fully use the network.
For a TCP receive window that has a particular size, you can use the following equation to calculate the total throughput of a single connection.
Total achievable throughput in bytes = TCP receive window size in bytes * (1 / connection latency in seconds)
For example, for a connection that has a latency of 10 ms, the total achievable throughput is only 51 Mbps. This value is reasonable for a large corporate network infrastructure. However, by using autotuning to adjust the receive window, the connection can achieve the full line rate of a 1-Gbps connection.
Some applications define the size of the TCP receive window. If the application does not define the receive window size, the link speed determines the size as follows:
For example, on a computer that has a 1-Gbps network adapter installed, the window size should be 64 KB.
This feature also makes full use of other features to improve network performance. These features include the rest of the TCP options that are defined in RFC 1323. By using these features, Windows-based computers can negotiate TCP receive window sizes that are smaller but are scaled at a defined value, depending on the configuration. This behavior the sizes easier to handle for networking devices.

You may experience an issue in which the network device is not compliant with the TCP window scale option, as defined in RFC 1323 and, therefore, doesn't support the scale factor. In such cases, refer to this KB 934430, Network connectivity fails when you try to use Windows Vista behind a firewall device or contact the Support team for your network device vendor.
Review and configure TCP receive window autotuning level
You can use either netsh commands or Windows PowerShell cmdlets to review or modify the TCP receive window autotuning level.
Note
Unlike in versions of Windows that pre-date Windows 10 or Windows Server 2019, you can no longer use the registry to configure the TCP receive window size. For more information about the deprecated settings, see Deprecated TCP parameters.
Note
For detailed information about the available autotuning levels, see Autotuning levels.
To use netsh to review or modify the autotuning level
To review the current settings, open a Command Prompt window and run the following command:
The output of this command should resemble the following:
To modify the setting, run the following command at the command prompt:
Note
In the preceding command, <Value> represents the new value for the auto tuning level.
For more information about this command, see Netsh commands for Interface Transmission Control Protocol.
To use Powershell to review or modify the autotuning level
To review the current settings, open a PowerShell window and run the following cmdlet.

Autotuning levels
You can set receive window autotuning to any of five levels. The default level is Normal. The following table describes the levels.
If you use an application to capture network packets, the application should report data that resembles the following for different window autotuning level settings.
Deprecated TCP parameters
The following registry settings from Windows Server 2003 are no longer supported, and are ignored in later versions. Adobe application manager for cs6 mac only.
All of these settings were located in the following registry subkey:

Windows Filtering Platform
Windows Vista and Windows Server 2008 introduced the Windows Filtering Platform (WFP). WFP provides APIs to non-Microsoft independent software vendors (ISVs) to create packet processing filters. Examples include firewall and antivirus software.
Note
A poorly-written WFP filter can significantly decrease a server's networking performance. For more information, see Porting Packet-Processing Drivers and Apps to WFP in the Windows Dev Center.

Besides getting a speedy processor and as much RAM as you can afford, a Solid State Drive (SSD) also plays a very important role in making your PC fast. However, an SSD will stay on it best performance and last longer only if it's properly maintained.
TRIM is an ATA command set that was originally designed for the purpose of keeping a Solid State Drive at its optimal performance throughout its lifespan.
The TRIM feature allows Windows 10, or any supported operating system, to notify an SSD which blocks of data are no longer in use and can be safely wiped out to be writable again. Having this operation done ahead of time improves performance, as the drive won't have to spend time erasing a particular block when space is needed to store new data, ensuring the SSD reaches its advertised lifespan.
While the operating system should properly detect and enable TRIM automatically, sometimes this may not happen. In this Windows 10 guide, we'll show you the commands to make sure TRIM is configured and how to enable it when it's not.
How to check TRIM is enabled in your Windows 10 PC
Making sure that TRIM is enabled on Windows 10, you only need to use a command using the Command Prompt with administrator privileges.
Windows Auto Tuning Level
Explanation: If after executing the
fsutil command with the DisableDeleteNotify you get a result of zero (0), then it means that TRIM is enabled, and no further action is required. However, if after running the command you see a result of one (1), then it means that TRIM is disabled.
How to enable TRIM on your Windows 10 PC
When TRIM isn't enabled on Windows 10, you need to do the following:
After running the command, you will notice the same DisableDeleteNotify = 0, which indicates that the feature is enabled. https://skyeyspiritual.weebly.com/blog/mac-endurance.
How to disable TRIMEnable Auto Tuning Windows 10 Download
If at any time for any reason you need to disable TRIM, you need to do the following:
Enable Auto Tuning Windows 10 64
For TRIM to work, both the operating system and the Solid State Drive must support the feature, and it must be enabled in the operating system.
While we're focusing the guide for Windows 10, you can use the same commands on Windows 7 and Windows 8.x.
