Here is one of many posts regarding TCPAckFrequency, in case you haven't heard of it yet:
(Note: editing your registry incorrectly can cause problems, so use at your own risk and only if you're careful not to make unwanted changes.)
Also, when locating your Interface, there will be a list of them, look for the one that has your IP address in it, it should be obvious because the others will be full of 0's and a few interfaces might be 127.0.0.1 for example, but your IP is most likely something more random than that (ie 184.108.40.206) and that is the interface that you want to place these DWord values inside of.
If you do this correctly then reset your modem/internet connection, then you will notice improvements right away in your latency.
After installing Windows 7 I noticed a slight increase in network latency in several online games. It wasn’t a big deal – I’m talking 200-300ms, but this is on a connection that was reliably < 100ms in the past. Beyond the obvious settings in Windows or on your router, here’s a list of tweaks that may help quite a bit. It involves disabling Nagle’s algorithm, also commonly known as TCP no delay, which is basically an optimization of network traffic that tries to reduce overall packet volume but can cause extra latency in the connection. This should work on Windows 7 or Vista, though the same principle can probably applied to other operating systems as well.
This decreased my ping in most games from 200-300ms to 50-60ms, which matches the latency I would see via a tracert to the game’s server.

This can also be done using a simple script for those not comfortable messing about with the windows registry ;
Have to say i was really surprised how effective this was. Like Robscure, i was often getting 200-300ms in World of Warcraft, since using this have'nt seen a ping over 80, and thats in busy game areas like Stormwind. Most of the time ping now sits around the 50 mark.
I doubt this will do much for people with terrible 1k latency type problems, but if you have an average to poor ping despite otherwise good internet connection , this seems to do wonders for some.
