Hey guys I have read everything and have the exact same problem with LimeWire slowing down my computer. One thing I did notice though is that when LimeWire starts up at the bottom left-hand corner it lets you know how many files you are sharing, and everytime I start it up it like resets and slowly builds up to my 3000+ files. While it is doing this my computer comes to a crawl, but after it is done (which is like 10 minutes later) my computer runs normal. I guess if you want it to be fast you just shouldn't share files, but that defeats the purpose of the whole P2P thing. Anyways that was just something I noticed, I wonder if any of you guys have noticed that also?
