My 17"PB with 512mb ram and 60gig hd seems really slow! It takes about 3-5seconds to fully open mac osx help. In iMovie it takes about 8seconds to open a 3minute project. It took 3minutes to add a 2second earthquake effect. It took 12secs to add a 2second cross dissolve transition. It usually takes like 3-4seconds to close an app. Word takes about 6seconds to fully open. When opening a picture that is about 1.5mb it takes about 5 seconds. Is this what I should expect, or is there anyway to speed the system up without buying more ram(which I plan on doing eventually)? I mean a 1.6celeron with 256mb ram opened word in 2seconds compared to 6seconds on my computer. Will 10.2.5 speed up the system more? Is there some kind of system maintance I can run to keep everything fast and smooth? Thanks You so much in advance! I am completely new to macs, so any advice will be welcome....thanks again!
