I have a Pentium II at 450MHz, and I am sharing 1200 mp3 files. I've found that changing from 4 continuous connections to 3 connections has made a big difference. Also, sometimes Gnotella fails to shutdown the aFileDB task, and (on Win 98) I have to Control-Alt-Delete and then End-Task it. It is this task which is the "hog" of CPU resources.
