I have a Tyan S1832DL with dual PII 350s, 384 MB of ram, Adaptec 2940 
scsi controler w/Seagate ST39102LW disk, and a voodoo 3 3000.  I've been 
running ULE for a while now and have noticed that I don't have to be in 
X to see the scheduling problem, I don't even have to be in multi-user 
mode to notice.  Typing and executing commands in single user mode I can 
see the scheduling is not fluid.  For instance, I can type in and 
execute the sync command so fast that I'm finished before the characters 
actually get printed and the prompt returns.  I don't think it's ever 
been more than a one second delay, but sometimes it's been close.

Your dedication to FreeBSD is outstanding, I always look forward to 
seeing your name in the cvs reports.  Thanks for your efforts, Jeff.
