Massive lag spikes in arena (unplayable)

Right now I am 160 fps in the mall, usually 100 in bgs. And on other servers it never dips below 60, specifically on Gamer District where I climbed to 2k rating. In arena it was always a stable 100fps+.

But on here in the arena I've tried (2v2 skirmish) as soon as the match starts it becomes a nightmare. Crazy lag spikes. I've tried deleting the cache with no change.

I played around with the wtf folders to try copy over all the keybinds/settings, could this be a problem?

I am also running it on a mac 3.3.5a client (TPB Molten-wow client)

I really love the server, it would be amazing to get this fixed. I highly appreciate your help.

Fixed - Gladius was the problem. Disabling this made the lag go away (Incase someone in the future suffers from the same thing)
