Right - Limewire locks your memory until your machine is dead! I have an Athlon 1000@1040 (FSB 104) with 384MB RAM - I disabled virtual memory which is perfect for any app or game or whatever I use. Only Limewire blocks all the memory in about half an hour. I'm gonna try Gnutella again - had some good results with it some time ago on a PIII 450 with 128MB RAM (kept only 1 or 2 connections running, then the CPU util was a little below 100% - it also used a lot of memory!) Let's see how good it is now...
