comment Course of action to clean up RAM on sluggish mac
@Mark I get that, thanks. I would still expect to be harder to run out of RAM if the OS were releasing its cache. I suspect it does not really.

@Dempa The OS (plus launchdaemons) uses 5 GB after a reboot. It does not leak and take more than that. However, I don't see the OS caching etc. being smart, as apps seem to use only the remaining 3 GB, I don't see the OS flexibly releasing more as the apps run into, say, the last 1 GB of free RAM. With smart caching I would expect it to be harder to run down to 30MB of free RAM. But no, this is easily possible with a few apps open, as the apps seem to share only the 3 GB not free after a reboot, and never get back more than that.

@Dempa I use Chrome Canary with quite a few flags turned on, maybe it does eat a few GBs. But even in that case, I would expect Yosemite release some RAM if it was hoarding it only "just in case" while it could. When I am down to 300MB or less, I cannot accept the OS still taking up 5GB and not releasing it. That's not smart caching, that's a memory leak. What else is there to do to investigate?

Well, Chrome is a memory hog for sure. Easily losing 2 extra GBs from the 3 left free even if only 3 tabs are open. Many other operations are sluggish, esp. the Finder (shall I suspect Dropbox?). I was suspecting disk intensive operations to be slow (esp. on a spinning HDD), but running down to 30-200 MB free RAM makes me suspicious that Yosemite is not that efficient managing caches and RAM. Or what could I check for you, and how?

The extra Google stuff is not mounted (and Get Info knows only that their extension is .m): Laszlo-Sandors-MacBook-Pro:Volumes laszlosandor$ mount /dev/disk1 on / (hfs, local, journaled) devfs on /dev (devfs, local, nobrowse) map -hosts on /net (autofs, nosuid, automounted, nobrowse) map auto_home on /home (autofs, automounted, nobrowse) localhost:/p3gHt-AQlUd8simYiL6EqQ on /Volumes/MobileBackups (mtmfs, nosuid, read-only, nobrowse)

The extension is .m, apparently. I see no dmg mounted in my sidebar, I usually remove them.
