WoW Latency, DCing & Performance Information
UPDATE: #3 has been tested by many users and is by far the most helpful for anyone trying to improve their WoW latency.
The other day I experienced 1000-3000ms latency when normally I have 50-80ms. Not only that but I was CONSTANTLY getting DCed from the raid which isn't fun when you are the 25m MT so I did some research and thought I would share it here as well as on my guild's site.

I personally tested these changes I have returned to a full night of raiding with 50-80ms, no disconnects and no other problems. Hopefully this might help some people resolve their issues without searching everywhere for things to try.
I. Finding your WoW server IP address
For testing purposes it is really important to have an IP that you can trace so that you can see if problems are a result of your ISP or elsewhere in the route to your game server.
Here is how to see what the IP to your WoW server is (PC based):
1. Login to WoW and connect to your normal server
2. Press alt+tab to minimize WoW and return to your desktop
3. Click 'Start', 'Run' then type 'cmd' and click ok
4. Type 'netstat -n' and wait until it finishes and the command prompt appears again
5. Find the IP address connected on port 3724 for example: xxx.xxx.xxx.xxx:3724 this is the IP to your WoW server
If you want to run a trace to that server do the following:
1. Click 'Start', 'Run' then type 'cmd' and click ok
2. Type 'tracert xxx.xxx.xxx.xxx' where the x's are the IP address of your WoW server (don't include the port 3724)
**Note** If you prefer you could type "tracert xxx.xxx.xxx.xxx > "C:\trace.txt" in the DOS window to have the trace saved to a 'trace.txt' file.
Blizzard has pinging functionality and the last few hops of a traceroute disabled to prevent attacks, don't worry that after the first group of hops in your trace to the WoW server the connections will all time out.
II. 3.2.2 DCing & Terrible Latency Fix
Here is a potential fix that has worked for some people (XP instructions but Vista should be similar), it mostly works for home users not so much for people on college internet.
1. Right click 'My Computer' and select 'Properties'
2. Under the 'Hardware' tab click the 'Device Manager' button
3. Under 'Network Adapters' right click your adapter and select 'Properties'
4. Under the 'Advanced' tab find the option for 'Flow Control' and enable it
5. Under the same 'Advanced' tab find the option for 'Speed and Duplex' and set it to '100 Mbs Full Duplex'
This really depends on what modem and connection you have, basically if you have 100 Mbs Full Duplex available you should use it. You should be able to leave it on 'auto negotiate' but some don't work correctly and it helps to set either Full or Half duplex depending on what you have available to you.
III. Leatrix Latency Fix (for PCs, read the wowinterface notes for a Mac fix)
I tried this latency fix and surprisingly it actually worked perfectly for me. I was averaging 180-300 pings while other games like Counter Strike I would have 30-65. After using this fix however, my wow latency is down around 50-80 http://www.zugzug-guild.com/forums/i...icon_smile.gif

Give it a try and see what you think, it modifies your registry for you so you don't need any advanced computer knowledge to do it. If you don't like the fix you can easily take it back off at any time.
Read the included notes on the wowinterface page for full details and explanation of how the fix works and what exactly it does. There is no danger to your computer and the fix can easily be removed.
IV. Additional Tips
- Fubar Addon Spam Fu: tells you who has addons going crazy overloading your connection
FuBar_AddonSpamFu - Addons - Curse
- Get rid of Quest Helper
- Disable as much as possible from your combat log filtering (you can still run /combatlog to record raid info to post to wmo or wws since it is separate from your in-game filtering)
