Like the title says, I'm just curious.
Leatrix Latency Fix
Its not that I'm worried this is a spyware or something. I'm sure WoWInterface will shut it down long ago. Just wondering if anyone uses this or tried this addon? Is it even worth installing?
What does it do?
Leatrix Latency Fix will reduce your World of Warcraft latency significantly by increasing the frequency of TCP acknowledgements sent to the game server. For the technically minded, this is a script which will modify TCPAckFrequency.
You will also see reduced latency in other online games such as Aion, Warhammer and Lord of the Rings. The average reduction in latency (based on feedback from comments) is 66%. Click the Change Log tab above to see a summary of player feedback.
Leatrix Latency Fix is supported on these operating systems only.
Windows XP (SP2 or higher)
Windows Vista (SP1 or higher)
Both 32-bit and 64-bit versions of Windows are supported.
Macintosh users should read the relevant section in the FAQ below.
How It Works
Wow uses the TCP protocol which requires that network segments sent to your computer be acknowledged in order to provide a reliable connection.
Windows bundles these acknowledgements together and sends them in pairs. While this is an efficient way of dealing with them generally, the inevitable delays caused by the bundling process increase latency considerably.
This is because when Windows queues up an acknowledgement in order to bundle it with the following one, the game server has to wait for the acknowledgement timer to expire before sending new data.
Leatrix Latency Fix removes the acknowledgement bundling process so that an acknowledgement 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.
In a normal networking environment, you would prioritise network efficiency over latency and use the Windows defaults, but in Wow the opposite is true and you want the lowest latency you can possibly get.
