I have a few ideas but I really do not know what is going on. My iMac core duo with leopard and 2Gb of ram is the one running slowly. When looking at activity monitor the system memory is always being used with lots of page outs. The hardware is all the same as my macbook however it is running snow leopard. just comparing the two computers activity when running the same programs the iMac has over 3 pages of things running while the macbook has a little over one. Aside from safari the top ram using programs on the iMac are WindowServer kernel_task DashboardClient,Dock which all use over 100mb of ram and mds which uses over 50. The only one of these programs that is one the macbook is dock and it uses a tenth of the ram there. The other troubling thing is the user of the programs. On the macbook every program has me as the user on the iMac I am only the user for about 2/3 of the programs most of the other user is root but there is also window server spotlight mdnsresponder and daemon. We took the computer to apple genius a few weeks ago just saying that it was very slow. All they did was delete some cache files and ran diagnostics on the hardware which were all good. I am not sure if any of these things are actually the problem but I am sure that there is something wrong.
