iMac DV, 450 hz, 320 ram, OS10.2.6, LW 3.02, DSL

Prefs set; sharing iTunes (2400+), cable/DSL, disable ultrapeer, search limit 15, 4stars only, all speeds, disable compression, port 6346, force IP

1. It take 5 mins. to finish counting all the files too share, but if I add one file, it then takes 30 mins... why? and everything slows way down until that number of files sharing are counted....

2. If I have more than a few (4) searches going concurrently, the app disconnects, doesn't respond to connect under file.... sometimes with in 5 mins, maybe 20, no pattern, I must quite & restart....

3. when LW manages to stay up, less than 25% of the file actually download, most end up "awaiting sources" and these are ALL 4 STARS!!

help Steve

ps. is there a step by step somewhere on how to set/check permissions? also firewall???
