I have a Macbook Pro 17" 2.8 with 4GB of ram running 10.7.2 For maybe the last month or so, the finder (do we still call it that?) has become very slow. If I reboot and repair permissions, it speeds up for a day or so, then becomes slow again. Simple things like opening folders, copying small text files, moving a folder to the desktop,etc. take forever..... around 5-10 seconds when they should be instant. I tried Activity Monitor and nothing is amiss. No MacDefender installed, so that's not it. Any ideas? PS: I have 8GB of ram on order, but this was never an issue before.
