1: Skillfully use the master of optimization, and the network speed will increase to your highest point. Principle: If the MTU of this machine is greater than that of the gateway, then the large data packet will be split and transmitted, resulting in
Many data packets are fragmented, which increases the packet loss rate and reduces the network speed. Setting the MTU of this machine to be less than or equal to the MTU of the gateway can reduce packet loss. Fill in the transmission unit buffer: 262080.
It has no effect on the system, that is, it is effective or invalid. By setting, optimize the receiving buffer of the computer and change the maximum transmission unit (MTU) of the network. Acceptance is easier to understand.
The maximum data packet (in bytes) transmitted on the network. The specific steps are as follows: 1. Reserved bandwidth change: (release 20% of the reserved bandwidth) Remember that it will enter when operating.
Gpedit.msc goes to management template-Network-QOS-Limit reserved bandwidth, and changes the value from 20 to 0. Two. 1, open the optimization master, select system optimization 2, and select optimization master's.
Network system optimization. Fill in the maximum transmission unit size: 1492, maximum data segment length: 1452, and transmission unit buffer: 262080, such as PPPoE(ADSL).
The best ones are: 1492, Ethernet: 1500, and dial (modem): 576 4. Click to optimize 5. Restart the water of the machine. 2. Really improve the network speed!
(Experience sharing, the effect is obvious) Many other netizens' methods have been used. Comparatively speaking, only this method can really speed up the opening of web pages! Especially opening web pages with more pictures,
The speed of opening the web page before and after using my method is completely different! But let's be clear: it's just that the speed is much faster at first, and it will drop after a few minutes. In fact,
Enough! Just like you get on a crowded bus, if you stand well, you will get on it easily, while others will find it difficult or even impossible! Friends with slow internet speed want it
I've encountered some situations where some web pages can't even display additional code. If you use this method, you will get immediate results! Try it, you will be surprised! ! The method is as follows: (If you don't believe me,
You can back up the registry first. I've been through it many times and I don't think it's necessary! ) 1. Run "regedit" to open the Registry Manager; Then, find it along the following path.
HKEY _ local _ machine \ system \ currentcontrolset \ services \ tcpip \ Parameters.2. Right-click the corresponding blank to the right of the "parameters" subitem.
Select the New →"DWORD value and name it DefaultTTL. Then, right-click the mouse, select Modify, and modify its value to 80 (hexadecimal) in the pop-up window.
Or 128 (decimal). 3. Create the following DWORD values in turn and modify their values (if there are two values, the former is hexadecimal and the latter is decimal):
EnablePMTubhdetect = 0 EnablePMTudiscovery =1globalmaxtcpwindow size = 7 FFF or 32767.
(I changed it to 372300, followed by this setting) "tcpmaxupacks" = "2" "sack opts" = "1""TCP1323 opts" = "1""TCP windowize" =
"7FFF" or "32767" (93440 or 186880 or 372300, depending on the network situation) is the water outlet area. 3. The way to improve the network speed is to play regedit to.
HKEY _ local _ machine \ system \ current control set \ service \ tcpip \ parameter adds a DWORD named GlobalMaxTcpWindowSize.
Change the value to 360000, the decimal to 360000, the decimal to 360000, and add the decimal to the DWORD named Tcp 1323Opts.
Change it to 1, select decimal to add DWORD named DefaultTTL, change it to 64, select decimal to add DWORD named EnablePMTUDiscovery, change it to 1, and select decimal.
The new DWORD named EnablePMTUBHDetect is changed to 0, the new DWORD named SackOpts is changed to 1, and the new DWORD named Decimal is changed to 0.
Change the value of TcpMaxDupAcks to 2 decimal places, and then go to HKEY _ local _ machine \ system \ current control set \ service \ tcpip \ parameter \ interface \ interface.
(This interface needs to add its own interface, and the new key is called interface. The new DWORD is called MTU, and the value is changed to 8000 (if10m is used)1500.
(If 1.5M is used) Enter HKEY _ User \ Default \ Software \ Microsoft \ Windows \ Current Version \ Internet Settings after the decimal point of 2000 (if 3M is used).
The new DWORD named MaxConnectionsPerServer is changed to 00000 100, and the new DWORD named maxconnections per1_ 0server is changed to 00000 100.
After choosing decimal, the broadband speed is increased by 50 times to win XP. Win XP's network transmission settings do not give full play to the limit of broadband internet access performance. 4: Run the input.
Regedit found that HKEY _ current _ user \ software \ Microsoft \ Windows \ current version \ Internet settings changed ie's default thread to these two.
The default value is 10( 10 radix). Change it to over 50. Same. The water that exceeds the maximum number of connections per 1 _ 0 server of MaxConnectionsperserver is blue.
5.Windows XP comes with PPPoE dialing, which optimizes the network connection more comprehensively, so the places we can optimize are greatly reduced. According to the current official information of Microsoft,
We can still optimize and adjust the following places. 1, open the registry editor (start menu->; Run-> Enter regedt32.exe-> Ok)
Add the following values to the following items: HKEY _ local _ computer \ system \ CCS \ service \ ndiswan \ parameters \ protocol \ 0Add the following items to this item.
Only two key values can effectively modify the MTU parameter of WindowsXP * * * Name: Protocol Type * * Type: REG_DWORD Double Bytes * * * Key value: 0x00800 * * * *
Name: PPPPProtocolType * * * Type: REG_DWORD double byte * * Key value: 0x002 1 Now you can add the key value for controlling MTU * * * Name: ProtocolMTU * * *
Type: REG_DWORD double byte * * * Key value: 1492 ADSL PPPoE users generally set the MaxMTU below 1492 and enter the correct value according to their own test results.
2. According to Microsoft's database, we can directly use the following optimization modifications to add the following values to the following projects:
HKEY _ local _ machine \ system \ current control set \ service \ tcpip \ parameter sack opts = 0000000 1 (double-byte DWORD value)
TcpWindowSize=0003e640 (double-byte DWORD value) TCP1323opts = 000001(double-byte DWORD value) DefaultTTL=00000040 (double-byte DWORD value).
EnablePMTUBHDetect=00000000 (double-byte DWORD value) EnablePMTUDISCOVERY = 0000001(double-byte DWORD value)
GlobalMaxTcpwindowsize = 0003EBC0 (double-byte DWORD value) If PPPoE connection is used, 0003e640 is recommended.
