Could also be other issues unless you see this specific set of symptoms. Mine gets sluggish but it seems to have something to do with the 'systemstats' process.

Could also be other issues unless you see this specific set of symptoms. Mine gets sluggish but it seems to have something to do with the 'systemstats' process. When I open up something that queries it (e.g. click on the power icon in the menu bar to make it go to "Collecting power usage information...", or open Activity Monitor), it goes nuts, pegging the CPU and ballooning to >2GB of memory. Haven't figured out what to do about that, besides kill -9'ing it and avoiding doing anything that'll cause it to respawn.
