Uploads seem to make almost no progress at all. 2.6.3 was the last version that I used that uploads performed properly under. Under 2.6.5 and all 2.7 versions, I notice that almost all uploads show 0kB/s. Very infrequently, one will show 1kB/s.

The upload rate-limiting feature is turned off. I have sufficient outbound bandwidth and have attempted to transfer files between two computers that can normally transfer hundreds of kB/s between one another, and the transfer always makes almost no progress.

Mac OS X 10.2.1 on iMac G4/800 (configuration unchanged since 2.6.3)
LimeWire 2.7.3

Hm?
