Hmm… I have an irritating Mac as well. It seems very slow. My problem I’ve been told is the way I’ve set up my four terrabyte system… I just did it as one big Raid volume. Apparently a dumb idea. You need a separate System Disk and as the man said above, move the scratch disk to a separate disc.
I haven’t got round to reformatting and reinstalling everything yet… boy am I looking forward to that! But essentially if after doing that and i’m still having problems of this nature, it means the Mac isn’t working as it should.
Since all the tests i’ve done indicate the Mac is OK, then everything points to the disk configuration.
