Just a quickie, but for a while now I have been experiencing really slow boot and shutdown times in Leopard. I looked on all the forums and lots of people seemed to be having the same problem. I consulted the system logs and found lots of scary looking errors, but after searching the forums again, I decided that the stuff in the logs was, in fact, normal.
The official Apple advice for this issue is to do an “Archive and Install”, something which I had not wanted to try, but last night I did it. No difference at all, except my Apache web server configuration went hinky and had to be restored. Then about ten minutes ago, I found an entry on a forum which suggested that iStatPro was causing the slowdown in some cases. I ditched the widget and things are *much* faster. iStatPro, more like iStatSlow!
