Disabling Nagle Algorithm
In a nutshell it was designed for older dial-up modems to prevent online games and other things sending numbers of small packets from hogging up your bandwidth sending 'ACK packets'.
What this does is automatically delay your computer from responding to a single packet by 200ms, which allows your computer to respond to multiple packets at once using less bandwidth; what this does, is add up to 200ms to your lag.

We can drastically decrease your lag by disabling the 'Nagle Algorithm' with a simple registry change as follows: WinXP/WinV/Win7 32bit/64bit
For all MS Windows OS
Run regedit
Access this by pressing the Windows Key+R together or Start/Run, type the word regedit
Browse to: HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\Tcpip\Parameter s\Interfaces\
In this drop down you will have 1 or more folders with a bunch of numbers and letters; each of those represents a network adapter in your PC.
Choose your adapter if you know how to identify it.
Add the following line to all of the folders if you are unsure.
Add a DWORD named TcpAckFrequency (This is Case Sensitive)
Set the Value of the DWORD to 1
Add a DWORD named TCPNoDelay (This is Case Sensitive)
Set the Value of the DWORD to 1
Reboot your PC!
After this, the Nagle Algorithm will be disabled.
Congratulations!
Now to test if this has made a difference for you, log into 9DVN or any other game you experience lag in, and throw a few buffs or nukes, you should see and feel a huge difference.

Automated Scripts
LLF removes the acknowledgment bundling process so that an acknowledgment is sent immediately for every segment that's received. This produces a significant reduction in latency as there is no longer a delay before new data is sent to your computer.
@OP The lagg reduce thingi didnt work for me :-( same lagg as before.. idk why I got such good internet + PC >_>
It's very heavy online at the moment, it's 7pm there!
I have had a huge improvement at least I can do alot more things than locking up all the time; especially around alot of grinders and heavily spammed maps!

LLF is this, just automated, I was going to put it up, but meh!
It only adds the TcpAckFrequency line, not the TCPNoDelay line, so you still have to add this manually.
Edit:
Leatrix Latency Fix Added to Automated Scripts
had the opposite effect on Win7
Once i added it, it would constantly disconnect my 9DUS game.
I never DC in 9DUS, i wasn't even able to stay on for an hour without dcing
for those who complaining about lag,it's common if u run the hack with 9d but if u not,then the problem is ping woops high. this is cos we are far from their server. to tell u the truth,my brother runs 9d with 384k speed connection with mid value PC.i never experience lag too it cos i'm near with their server. sorry not trying to off topic or watsoever,just it worthless to ask why i 'm getting lag..........
Latency Fix 01/07/2010 - 9Dragons - 3 Replies If you're using your skills and there's a 1-2 second delay before your character uses the skill you can attempt to 'fix' it by downloading and installing Leatrix Latency Fix.
It made my skills response time much faster, every time I go to cast a nuke now the game almost instantly starts using the skill. Give it a try if you're getting a lot of lag issues.
You will need to restart your computer after you've installed it.
[Need Help] Reduction Bot 08/23/2009 - General Gaming Discussion - 5 Replies I wanted to make a script that controls your mouse and reduces the items in your bags for you since it's quite boring having to reduce 99 items manually.
I used Auto It 3 to make the program and it works fine outside the game, but when in the game the game either crashes with a hackshield error if it's already compiled or the mouse doesn't move if it's run before compiling.
Now before you accuse me of spreading viruses, I know it's my first post and it's suspicious, but I've added the...
