Thanks, this looks like it. I was wondering, who is actively involved with measuring scheduler performance on FreeBSD? FreeBSD scheduler gurus may want to take a look at the Hourglass tool written by John Regehr at University of Utah: http://www.cs.utah.edu/~regehr/hourglass/ Hourglass has been used to measure scheduler performance on Linux, FreeBSD 4.x, and Windows 2000.
