I complained about poor interactive performance of ULE in a desktop
environment for years. I had numerous people try to help, including
Jeff, with various tunables, dtrace'ing, etc. The cause of the problem
was never found.

I switched to 4BSD, problem gone.

This is on 2 separate systems with core 2 duos.
