Demystifying Windows Server 2008 Optimization Pseudo-Tips

  
        

Windows Server 2008 is a server-based operating system. Nowadays, many system enthusiasts have optimized, streamlined and tailored Server 2008 into a personal version of the operating system. There are quite a few optimization techniques on Server 2008, but there are some fake techniques. Some communicators have not been rigorously tested to rumor, and users are blindly used when they are unknown. The result is not only an increase in system performance, but also unpredictable system errors and even system crashes. Therefore, it is very necessary to implement technical anti-counterfeiting to extract these system optimization pseudo-techniques.

Pseudo-Tip 1: Disabling "reserving bandwidth" will result in improved network performance

The pseudo trick is to run gpedit.msc to open the Group Policy Manager and then navigate to “ Computer Configuration & Rarr; Management Template & Rarr; Network & Rarr; QoS Packet Planner & rdquo;, found on the right side of the "restrict bandwidth can be reserved" option and disable it can bring about 20% improvement in network performance.

In fact, from the era of Windows XP, this proved to be a pseudo-technique. And in Microsoft's technical document KB316666 it is clearly stated that many published technical articles and newsgroup articles have repeatedly mentioned that Windows XP usually reserves 20% of the available bandwidth for QoS is wrong. But in the era of Windows Server 2008, there are people who are talking about fooling the public.

Pseudo Tip 2: Disabling the TrustedInstaller Service will improve network performance

The pseudo trick is to run Services.msc to open the Service Manager and find the "Windows Module Installer" item in the list of services. Stop the service and set the startup type to "disable" or "manual", which will release system resources and improve network performance.

The TrustedInstaller service is only available from Windows Vista and is used in Windows Server 2008. TrustedInstaller is the service name and its full name is Windows Module Installer. Normally, the service is silent. The Windows Modules Installer service will run automatically only when Windows Update is installed, or when some installation packages released by Microsoft are installed, so that system files can be modified or replaced. Therefore, the TrustedInstaller service is an important service of the system and is essential for the safe operation of the system. Turning off the service has little to do with system and network performance improvements, but it can cause unpredictable system problems. Disabling the TrustedInstaller service to improve network performance can be said to be a waste of food.

Pseudo Tip 3: Adjusting NIC properties can bring improvements in network performance

The pseudo trick is: Execute & ldquo; Start & Rarr; Set & Rarr; Network Connection & rdquo;, then Open “ Local Connect to the properties window of the ”. Click the “Configure” button under the “General” tab to set the network card. Under the “Advanced” tab, set the “Speed ​​and Duplex” value of the network card to “100 MB Full Duplex”. ”. After this setting, the network card will work at full speed at 100M.

Is this true? Anyone with general network knowledge knows that the speed of the network is not determined by the network card. The network card can only work on the basis of the existing network bandwidth, because the actual network speed of the network card limitation must be lower than the theoretical network speed. The above changes are nothing more than a cover-up, self-deception. By default, the speed of the network card is 10/100M adaptive, which is automatically adjusted according to the network speed. Such modification deprives the network card of the automatic adjustment of the network bandwidth according to the actual network bandwidth, which may cause the network card compatibility transmission failure.

Pseudo-Tip 4: Optimize the number of TCP connections to improve download speed

This pseudo-trick is: use the system optimization function provided by Thunder and other download tools to TCP/IP for Windows Server 2008 The number of connections is modified to ensure that the download tool can be downloaded at a high speed with multiple threads. In addition, the initiator of this pseudo-technique has also described in detail the use of tools provided by the network to modify to increase the number of TCP/IP connections for Server 2008.

This pseudo-technique is not self-defeating. It is estimated that some good people take it for granted, and they have made it out of the door. They have not tested it and used it to fool people! Windows Server 2008 is a Server version. Operating system, will it restrict TCP connections?

Pseudo-twork 5: Turn off the firewall to reduce shared access interference

The fake trick is: because Windows Server 2008 built-in firewall is enabled by default, in When a shared access is made, the firewall checks and verifies the access operation, which makes the shared access slower. Therefore, in order to speed up network access, you should log in to the system as an administrator, then enter the Windows Server 2008 Network and Sharing Center interface, and then turn off the firewall.

After shutting down Windows Server 2008, can the firewall speed up shared access? The answer is no. Because the shared service is enabled in Server 2008, the built-in firewall of the system is allowed to share access by default. If the firewall blocks shared access for some special reason, we only need to set the firewall to allow shared access. This way the firewall does not care about shared access when sharing access. The above mentioned firewall will verify the shared access, which is a assertion of the Windows authentication mechanism and take it for granted. In fact, shared access authentication between clients is system-based authentication independent of the firewall. Therefore, turning off the firewall will not only bring about an increase in shared access speed, but also may pose certain security risks.

Pseudo Tip 6: Turning off Autotune will increase network speed

The pseudo trick is to run cmd as an administrator in Windows Server 2008, then enter and run the command "netsh int tcp Set global autotuninglevel=disable” Turn off the AutoTuning feature in the TCP/IP stack to greatly increase the download speed of applications that support multithreading such as Thunder, BT, and make the network more stable.

In fact, this pseudo-skill has been widely spread since the era of Vista. It is used to solve the problem that Internet Explorer slows down when Internet Explorer opens certain websites and receives an error message. In fact, the author's test plan in Vista did not bring about an improvement in network performance, which also confirmed the doubts of many netizens. Now there is a life-long extension of this pseudo-trick to Windows Server 2008 to mislead everyone as a network optimization technique. In fact, the so-called TCP tuning function is a self-regulating mechanism of the TCP/IP stack. It adjusts the buffer size of the local TCP/IP stack according to the bandwidth traffic of the sender and receiver of the network. It should be said that it is an adaptive TCP/IP. mechanism. Therefore, turning off automatic tuning will not bring about an increase in network speed, but will cause network instability.

Pseudo-Tip 7: Turn off "Microsoft Peer-to-Peer Network Service" to disable P2P downloads locally

This pseudo-trick is: Log in to Windows Server 2008 as an administrator and run gpedit. Msc Open the Group Policy Editor, and then expand “Computer Configuration & Rarr; Administrative Templates & Rarr; Network & Rarr; Microsoft Peer-to-Peer Network Service & rdquo;, find the "Close Microsoft Equivalent Web Service" item on the right side and enable the policy It is possible to disable local P2P downloads.

The so-called peer-to-peer network service in Windows Server 2008 is actually a network peer-to-peer service between clients based on domain or workgroup mode. This has nothing to do with the P2P download in the Internet, not to mention the current P2P software has the function of breaking the download limit, even if it is turned off, "Microsoft peer-to-peer network service" does not affect P2P download, but will bring LAN The trouble of client data interaction.
