I'm running 10.6.4 on an early-2008 MBP (see my siggy for the specs). Why is it that sometimes when I wake my MBP up from sleep, everything, the entire system is incredibly snappy and responsive, yet on other occasions apps such as Safari, Outlook, etc. take lots of bounces to open and OS X, too, seems kind of slow? It's really odd - just a couple of mins ago I opened my MBP after an approximately 6-hour sleep, and several apps (including Safari and Outlook) opened on 1 bounce (actually even before it even bounced once). But as I said, on other occasions Safari might take even up to 18 bounces to open right after MBP has woken up from sleep, and other apps likewise. Is MBP somewhat like people? When you wake us up from deep sleep we are all groggy and need several minutes to get back to the real world, so does MBP function in the same way? Haha. But seriously, does this snappiness have to do with the amount of sleep MBP does, i.e. the shorter the sleep span, the faster those apps will open because they are still saved in cache memory (or whatever that is)? Thanks for any answers in advance.
