I have a Macbook pro 2,4 GHz Intel Core 2 Duo 4GB RAM (5year old) and things are NOT snappy. After clearing all the caches things seemed to speed up for a while, but now not so much anymore..
I'm hoping a clean install wil fix this. Boot time is the same as snow leopard, but I've been seeing a lot of beach balls.
It's weird, apps seems to load faster for me, but copy/pasting stuff is slower.
Maybe it's my express card driver that needs to be updated.
I thought my laptop would survive one more OS refresh, but at the moment it's been a little frustrating from time to time..
Beach balls occur when all RAM is used, but activity monitor isn't show what is causing the memory hog.
I have to reboot every now and then..
