UI Addon Memory Usage question!

Post by Razmortis

Hey guys.
Is there any way for me to find out what UI addon is sucking up the most memory? I have a good computer, but if I turn off all addons I get a significantly higher frame rate, and the loading time when starting up the game (loading the UI for the first time that session) is almost instantaneous.
I want to know what I can get rid off or replace.

You can use something along the lines of Performance_Fu to get a list of addons and the memory usage.

CPU usage impacts framerates. Not static memory usage.

and typically with wow addons, high memory usage means higher CPU usage.

Questhelper, auctioneer, recount all use a larger amount of CPU.

That's a terribly gross generalization, and a really, really bad way to look at it.

And your examples couldn't be worse. All three addons need to store massive amounts of data, resulting in high memory consumption. (Look into Lua tables -- the amount of memory index references cost increase at an exponential rate as you store more data.) QuestHelper particularly is just poorly coded. And Auctioneer has to do lots of calculations during dedicated scanning times, but uses zero CPU during actual play.

Razmortis: If you actually notice a change in play, then enable CPU profiling and mind the amount of CPU different addons take. But keep in mind some addons may only use high amounts of CPU during non-critical times when overall CPU usage is low anyway (such as the custom tooltip PerformanceFu itself uses to display its info, which only sucks up resources when it's shown).

This can all be done through PerformanceFu, or OptionHouse. I believe they both contain a button to enable CPU profiling, and can sort addons by CPU consumption.
