My interface lags for a second or so every time someone joins/leaves the party/raid or zones in or out. I suspect this has to do with XPerl's raid functionality (after trying to research some on the topic). Verifying that has been problematic, since it seems to be a combination of mods that are causing it.

I'm curious if there is a method of finding out what calls are being made that are causing the UI lag. I keep things up to date, and try to keep my UI fairly consistent as far as mod makeup and layout goes. But I'd like to find a good way to debug problems like this (when they become problems). Does anyone have any suggestions on how to track this? Maybe there's some nice debug tool that you love?

There didn't seem to be a thread on actual UI debugging yet. If there was and I missed it feel free to lock/heap. Thanks.

This exact same thing started happening to me this week, and it has happened before. The first time it was Deuce Commander. This time I've used KLH Performance Monitor to narrow it down to an ace2 event, which isn't that narrow. I'd also like to know how to granulate my results rather than turning ace2 mods off one at a time until I find the bugger.

I have brought this issue up awhile ago in this thread: Odd Raid...

I have managed to fix it by removing SavedVariables folder and let my mods rebuild it, after that I simply copied over my Gather.lua file and reconfigured all other addons.

That sounds painful. I'd really rather not reconfigure all my addons. There has got to be a better way to track WHICH SavedVariable is causing it and eliminate only that one.

I'll try cleaning the folder some tonight, I definitely don't have time this evening for a full UI rebuild though.

If the issue isn't critical at the moment, I would suggest just ignoring it until patch 2.1. With this patch, you will be able to get per addon memory and performace profiling which should help narrow down troublesome issues like this.

I think Niagra was doing it for me, very similar to Deuce Commander. If you have any addons that are like Ace2 control panels they seem to freak out every once in awhile.

Any addons that handle this out yet? I'd love to see individual cpu usage on Ace2 addons.

PerformanceFu seemed to track per addon memory usage. It only showed the top 3 I think but I didn't really look to see if I could configure it.

Really helps in tracking down memory hogs, forgetting to nuke swstats for example.

I think Fubar_Usage (from wowace.com/files) is what you're looking for. Shows cpu usage for each addon and has some sorting options. Was interesting to see KTM was #1 cpu using addon even while idling in Shattrath, with my unit frames (AG) coming second.

You can configure it to show up to 20, and it's also possible to enable CPU Profiling of addon usage as well (CPU Profiling is probably more key to figuring out performance bottleneck, than memory profiling is). The CPU Profiling is disabled by default because having it on will cause a performance hit, I recommend trying that out on some content that's trivial for you.

For example, my two largest memory consuming addons still consume relatively little CPU time, while KTM, which has a low memory footprint, takes up most of my CPU time, oddly enough even when I'm flying around doing nothing.

(Edit: Actually Ace2 is my largest memory consumer and cpu time consumer, but as I'm running stand-alone ace libraries and run ~60 Ace mods that's no wonder)

I've been having problems since the 'click sound raid lag bug' getting ctpartybuffs and grid (or prat which i no longer use) to work together nicely.

Seperately ctpartybuffs and grid work fine, put them together, and you get the split second delays whenever the raid adds/boots someone or if someone in the raid zones etc.

It drives me crazy because I can't find a simple ui mod that allows me to just have the old style bars (i place hp/mana totals to the right of the bars, just have the % on the bars), that also allows me to see party buffs. (Simpleunitframes doesn't show party buffs).

I started to dabble with the new archeologist but I get popup errors every time i target something.

This is what I'm used to using as my party frame:



(and i have portrait damage (shows inc hits/heals on the portrait) from simpleunitframes.

BTW, if you use script profiling to figure out whats wrong. Make sure you disable script profiling when you done since it has a pretty negative hit on performance.

Just do the below to disable it again.

/script SetCVar("scriptProfile","0")

And the usual kicker: Ace addons attribute some of their CPU time to the libraries, so Ace addon load tends to be higher than what's directly attributed to the addon (i.e. if you nuke an addon, not only do you lose that addon's load, but also some portion of the generic library load, depending on how heavily it uses the libraries.)

I had massive memory usage and terrible FPS after upgrading my Ace2 mods. I disabled everything but a few essential AddOns and saw no improvement. I thought it was the new ag_UnitFrames, but it turned out to be SWStats. Nuking the data fixed the problem, but I watched my memory usage steadily increase even after the data was erased. Totally disabling SWStats fixed all of my UI lag.

Killing off part of X-Perl removed the problems I was seeing (as I expected).

Baggins seems to be a popular choice for inventory management stuff.

I got the same issue but I don't even use SWStats.
Basically it's AGUF, Bartender, ORA2, sRaidFrames, clique

I don't know if this belongs here and how many people share that issue, but after raiding with constant 40-50 FPS I had an awful Magtheridon where I had 2-5 FPS the whole first phase.

While others didn't have the problem I figured (who'd not ..) that it's one of my addons but I can't find out which. Would be cool if people who have the same problem share their experience

I've written a solution to the idle KTM resource usage: Kill your extraneous KTM CPU usage

Give it a shot, and let me know how it works out for you.

Does anybody else's FuBar seem to use an absurd amount of memory and CPU time? Mine is currently using double the CPU time as my ag UnitFrames does, and is using about triple the amount of memory.

Edit: it occurs to me that the FuBar plugin I'm using to track performance data could be the culprit, but wouldn't that track under the individual plugin, and not FuBar itself?

Quick way to test that would to get a stand alone mod to list performance, anyone recommend a good one?

PerformanceFu can track memory and CPU usage.
