Are there any way to check out which addon causes performance degrade?

After latest update i am having lag problem (not network related)

Not really.

Is it lagging all the time, or just in specific situations? Does disabling all addons fix it?

If so then disable half to find the half that is repsonsible, repeat until you found the problematic addon ;)

that sucks

it can be cumulative lag of several addons

it started heavily after latest update

most seems like caused by Awesome UI addon

Normal addons shouldn't cause noticable lag while doing nothing though. Most should only do things on demand.

Mostly using the combat events can cause major performance decrease. Some addons do a lot of stuff for each event in which can cause huge performance issues if they add up.

That's why I asked if it lags all the time or only e.g. while fighting or beeing near people fighting. And do you mean the addon Advaced UI? Because that updated recently and maybe that started your problems then.
