When LimeWire is uploading at the limit of my connection, then I get no downloads. This could be an ISP issue, but my AsynchronousDSL line manages to be two way up until the limit.

Usually setting the upload speed to a little below my theoretical maximum fixes this unless one or two high speed connections take up all the bandwidth themselves.

It looks like limewire's message handling is getting caught in a wait state when there isn't enough bandwidth to send data as fast as it is being asked for (or summat).

This could be specific to my ISP - but it might explain some of the problems others have reported with not being able to stay connected to peers or ultrapeers (with very little download speed left, the peers get dropped as well as losing speed on file downloads).
