In short all it does it adds TcpAckFrequency to the registry with the value of 1.

The problem I found when I google is that most are about "how well this works" and not much research or real evidence if it works or not, it looks mixed as some say it works and some say it don't. The factors are many, the reasons are many too, in any case;
There are many registry entries one could tweak around to alter how the network works tough the TcpAckFrequency is perhaps most safe to change. Chances are if Leatrix adds a ton more variables it may cause problem for many and make people grumpy at the fix. :P
One thing I can say, the new leatrix patch made the vbs into exe, not longer as safe as before. I can't inspect the source before I run it, not cool.
