I haven't noticed and serious slowdonw on any of my 10.7 machines. The most common reason Macs 'get sluggish' immediately after a re-install or something like that is because the Spotlight indexing process keeps getting interrupted or the spotlight database is foo. Go to Activity Monitor and see what processes are chewing up RAM or CPU. If you constantly see 'mdworker' at the top, it's spotlight. Fire up Terminal and do the following. Replace /path_to_volume with /Volumes/<name of external drive> if you have external drives attached or just / to stop it on your boot volume. sudo mdutil -i off -a sudo mdutil -E -a sudo mdutil -i on / <Samuel L. Jackson Voice> And leave it the fuck alone </> This lets Spotlight do it's thing on a clean, unchanging file system, and once it's done rebuilding all it's indices, the mdworker process should definitely stop being a cpu hog. Do you have, perchance a Samsung printer? There's a bigass memory leak in their current driver in 10.7. You'll see the printtool process gobbling all the ram it can find. <https://discussions.apple.com/thread/3329492?start=0&tstart=0> Otherwise, again look to Activity monitor to see what's a RAM hog and what's a CPU hog. General sluggishness accompanied by lotsa disk activity means you have either insufficient RAM for your usage or theres a memory leak somewhere. One thing that'll bring your box to it's knees and beg for mercy is trying to run OS X and a Windows VM in not enough memory. If you're trying to run a Windows VM in a box with 4 gigs or less, particularly if you set up the Windows in the VM with the typically lowball memory allocation they give (512 megs for Windows 7...REALLY VirtualBox? You expect me to believe that shit will work?) you set yourself up for diskthrash hell. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are subscribed to the Google Groups "StrataList-OT" group.
