I realise that this computer has aged quite a bit but I'm still puzzled as to why is is running as slow as it has been. Basically it is a 2.2 GHz Intel Core 2 Duo with 2GB of memory. Running 10.6.7. I am having problems with it being painfully slow just web browsing and worse when I try to run other applications. I'm currently attempting to do some assignments using AutoCAD2011 but is it really slow going. The files that I am working on are not large at all, about 1MB. Activity monitor shows between 70-90% of the CPU idle (even when safari and/or AutoCAD are beach balling). It is also typically showing 400-500MB of system memory free. Finder also tells me that I have 14GB of hard drive space remaining (is this too little?). I've repaired permissions and verified disk in disk utility and it all comes up looking fine. Besides spending $$ upgrading is there anything I can do to improve performance for the time being?
