Is there any way to lower ping? - Page 2

Run the ping test from http://pingtest.net/


Where are you from?

Where are the servers you're trying to connect to located?

Also measuring the ping in game is the wrong way to do it, as some games show ping, some show latency and some even show a hybrid of it.

First thing u have to check is whether the server u are connecting with is using TCP or UDP protocol. If its using TCP i can recommend something ive been using for several years now.

1. From a command prompt (usually in All Programs -> Accessories -> Command Prompt) run “regedit”

2. Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Interfaces

3. Browse the items under interfaces until you find one that has an IPAddress entry matching the network interface you want to affect (typically LAN IP addresses start with 192.168 or 10.0); note that if your IP address is automatically assigned by a DHCP server you may need to look for a matching DhcpIPAddress instead of IPAddress

4. Right-click on the interface and select New > DWORD (32-bit) Value, name it “TcpAckFrequency”

5. Right-click the new TcpAckFrequency value and select Modify, enter “1″ (Hexadecimal radio button should be selected)

6. Right-click on the interface and select New > DWORD (32-bit) Value, name it “TCPNoDelay” (note that TCP is all uppercase this time – that’s intentional)

7. Right-click the new TCPNoDelay value and select Modify, enter “1″ (Hexadecimal radio button should be selected)

8. Verify that both TcpAckFrequency and TCPNoDelay now show up in the adapter’s property list with types REG_DWORD and values 0×00000001

9. Exit regedit and reboot (reboot is necessary for the changes to take effect!)

10. Play a game and enjoy your new low ping

To fully understand this u would need some network knowledge. When u are using a UDP connection ur computer keeps sending packets to the server with out delay in an constant stream. TCP works different however. When ur computer sends a packet it waits for the answer from the server that it got the packet and then it sends the next one. Microsoft however has always set the acknowledgement of these packets on a very low priority. Basically what u do know is force the server to acknowledge faster so u can send the next packet on its way resulting in an faster TCP connection.

Note that this only works for TCP connections as UDP doesnt work with acknowledgement.

Edit± Also i was assuming u are using Windows 7. So the steps i posted are for windows 7.

I remember reading that TCPNoDelay went elsewhere. Take a look at this link:

Scroll down to 'Gaming Tweak - Disable Nagle's algorithm' nearly 2/3 down the page.

Thats strange. He is recomending setting it to 1 where the 1 stand for disable. As far as i know in the windows registry 0=disable and 1=enable. So how come he recommends putting it to 1 for disabling it. That sounds kind of strange.

Assuming those are typo's hes saying exactly what i did.

According to MS a value of 0 is not valid.

Dont see if that aslo apply's to windows 7 tough.

Below is the best answer. In other words TCPNoDelay isn't found in the same location as TcpAckFrequency. And MSMQ key isn't created unless you enable/install MS Msg. Queue.
