The other day I discover that when the Horde and Alliance PvP on my server it lags the server out (If a horde guy attacks an alliance guy or vise versa everyones latency jumps up by a couple thousand MS). However, when a horde guy fights another horde guy (whether at an arena or through dueling) or an alliance guy fights another alliance guy nobody lags . So its not PvP in general its PvP versus the opposite faction that lags the server.
I'm using Ascent Rev. 3449
Average Server Latency=108
When people cross faction PvP average server latency jumps to around 2400
Any ideas on what's causing the problem and how to fix it?
-Thanks in advanced
