Slow performance

Running the latest limewire (downloaded yesterday), the user interface just crawls, taking many seconds, sometimes tens of seconds, to update.

On the other hand, downloads are faster now than with the previous version, much faster. Not quite as good as Fasttrack network, but getting there.

Here's one clue- under 'top', I see many, many Java processes. Could the performance sluggishness I'm experience stem from the java build I'm using, that it's running process-per-thread rather than internal threads? (I forget what Sun officially calls the two models.)

I'd gladly upgrade Java to get better user interface performance, but I have to say it looks like a typical Swing application -object and thread heavy, not as much concern for the user's experience.

My system: P-II 300MHz, 256MB ram, 32MB AGP video card, RH Linux 6.2 upgraded to latest glibc etc. My jre is 1.3.1, blackdown. The readme says it supports both native and green threads. Also says something about the JIT not being enabled be default. Could this be it?

thanks,
