Background:
P4 2.8C/1 GB DDR/128MB 8X AGP/W2K Pro SP3/Java 1.4.2_06

After doing some web research, decided to try out LimeWire! Downloaded/installed 4.8.1 and set my Kerio Firewall to enabled both TCP/UDP all ports/always both directions and I got connected!, however, for the first 30 mins my pc got SLOW down to a craw (CPU usage normal - less than 12%) min/max of LimeWire window took at least 5-8 secs and opening/viewing other folders took 10 secs......decided to reduce my share files from 75 to 20 (all 700MB - 1.5GB avi/mpeg files) and after about 30 mins everything was back to normal/super fast, took less than 1 sec to min/max LimeWire window, CPU usage less than 1%, Ram usage 14-18mb....WOW. (I incresed my share files back to 75 and no problem, so I would guess it's not the number of file shared!)

I managed to DL 3 avi files each about 80mb (to test)...however NO ONE is uploading from me???? Keep up the good work!
