As we know since 3.2-3 their have been many people faced with connection issues, TOC being one of the main gripes with wow players.

Here is a list of things that you can try to improve performance and latency.

1. LeatrixLatencyFix
Try this registry hack here – http://www.wowinterface.com/downloads/info13581-LeatrixLatencyFix.html

This does similar to my Latency Fix in that it adjusts the expected response between the server and client. This is perfectly safe and a good option if you are not techy enough for my solution. The key difference is that in theory linux has a much more efficient network stack and so you should see slightly better result (this is debatable)

2. Disable Bad Addons
Bad Addons I have defined as addons that are inefficienct or that spam ingame channels to share unneeded information. The reason the following modules should be disabled during raids is that they;

1. Are not needed for raiding
2. Affect your own performance due to high memory or cpu usage.
3. They send out a lot of data to shared ingame channels that affects other users (this has been identified as a contributor to dc issues in TOC etc).

If you would like an ingame get Addon Control Panel – http://wow.curse.com/downloads/wow-addo … s/acp.aspx
The bads include;

• Gearscore – spammmmmmmm, if you have this installed you should be gkicked
• QuestHelper – notorious for high CPU and member usage.
• Carbonite – a lot of messages and shit flying around
• Guild Location Mods – if you have a mod that tells you where guildies are, disable it (maps often do this to show your guildies on your map).
• Recount – If you use recount turn of Syncing! Or get Skada

this list will grow as we identify more fail addons

3. Set maxfps to something more realistic
Setting the maxfps to something like 30 can help when a lot of data is being sent to your graphics card (i.e. whelps or fire being thrown).
I have the following as a macro setup;

/console maxfps 0
/stopmacro [mod]
/console maxfps 30

4. Turn off Combat Log
turning off combat log realy helped me too, so you can give that a shot too
Hopefully this will help you

By the way: Tunza rocks!
