Yes. Smegma is right -- the problem is that Limewire scales very poorly, not that it doesn't perform well with a small load. Increase the hardware from your AMD 500MHz and 128 ram to something modern, and increase the demands you put on Limewire in proportion, and Limewire chokes. Somehow, either it doesn't utilize all the resources available, or it scales worse than linearly with the amount of files shared, amount of pending downloads, and such. Neither should be the case.
