The Perf Module, to me, is more a somewhat helpful in project indicator of what's up in regards to system resource consumption BUT certainly not the most accurate, nor reliable beast around.
1) I've actually requested (can't remember if officially or just in passing) an updated and more accurate perf module (like an exapandable more detailed view).
2) I've also noticed some out of place behavior recently that I'm not sure was because of an update and actual performance issues (Lexington) or increased Perf Mod inaccuracy or both.
Mostly though my point is that the Perf Module dropping out like that, without any other manifestations such as drop outs or crashes, probably isn't a huge deal. I view it more like a mercury/glass thermometer vs. a digital one.
To me though I would very much like (as I said) an updated and more detailed version that maybe shows exactly what Sonar is consuming itself (vs. the system or non audio related tasks), what's getting used by plugins, a better meter for disk i/o issues (as opposed to the current Yellow when all is well then a momentary and almost imperceptible RED when there is an issue which leads to a dropout and is my biggest issue) and... well whatever smarter techie folks than I can add in.
There are certainly other resource monitors that do this but not tailored for what we'd want to be looking at and those buggers tend to suck power themselves (and are not in APP like the Perf Module is).
I will keep an eye on it though. I've kept the Perf module in my Control Bar for ages now. If anything it let's me know when maybe I should start bouncing, freezing, archiving, etc. The Disk monitor is next to useless though because the Red status only blinks for a second before the project chokes on itself.
