I'm going to try and come up with a clean repro case... even if it relates to other apps... as Cog has a few times now been the only app 'acting up'. Might be nothing, but I am sure you'd like to see anyway. Thus far, it's hard to say what's going on. BUT, Just now it happened, and I closed Cog (it was 190% CPU), and decided to go back and sample it. Upon reloading, playing the exact same song (just to be safe), it's acting great, as it should. This is gonna be fun

I took a sample when it's acting up, and another when it's not, and to be honest... there's just nothing odd about either. The 'higher CPU' sample has fewer semaphore calls, but that seems fine, it's getting less 'clean timeslices', as the CPU is going nuts... so in essence, it's running at a 'lower framerate'. Nothing else is on the radar, etc... it just looks like 2 very slightly different samples of the same app. I thought I'd find it stuck on something, or hitting some odd call, but thus far, no. I will say, it seems like post-VMWare this is an issue, and clean-boot, before using VMWare, it's fine. VMWare on SL may be leaving my drivers in unhappy moods. Should I still pass these samples on, or just wait to see if things clear with OS/VMWare updates?

Re: Cog and Snow Leopard (19 replies, posted in General)
A recent upgrade from 8GB of RAM for my MBP has left a few odd things... and one seems to be Cog going _insane_, and playing files with 100%+ (dual core, I have seen it peak at 174% for Cog) CPU use. I myself am a developer, so if there's anything I can do to help zero-in on the issue, I am all ears. Cog is very much my de-facto player, and has been since I jumped to Mac dev a year or so ago. At this point, I am without audio while working, as 100% CPU isn't really useful
I forgot to mention... I left this in the SL thread because that's where I am, and I can't think of a better 'reason' for the CPU use, seeing as how Cog up until moving to SL a week or so ago was great. The combo of SL + 8GB is all that's changed.
