I have about 2000 mp3 files (12G) shared and limewire 2.8.5 pro (OS X 10.1.5) can take up to an hour to make them all available in the library. Part of it is due to changing files' ID tags via itunes.. I'm in the process of annotating and cleaning up existing tags as much as possible so it's easier to find things.. every time I make changes on a subset of files (say 40-50 out of 2000) limewire seems to be forced to reprocess the whole bunch, which is _painfully_ slow. It's a CPU & Memory hog too.. currently running at 30-40% CPU and 20% memory (of 256MB). I'm dying to try something else but options seem limited unless I get OS X 10.2... ..... .....
