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.I have reproduced the lagging mouse issue on my laptop. I tried moused to no effect. Eventually, I grudgingly installed kde and immediately started encountering problems with mouse lag. It would seem that twm was not stressing my machine in the same ways that kde is. ;-)
I suspect a problem with IPC. I will know more soon.Your dedication to FreeBSD is outstanding, I always look forward to seeing your name in the cvs reports. Thanks for your efforts, Jeff.
There have also been a few reports of problems related to nice. I was able to reproduce some awkward behavior but I have nothing conclusive yet.
There is still a known issue with hyperthreading. I'm waiting on some of john baldwin's work to fix this. If you halt logical cpus your machine will hang.
Expect some resolution on the ULE problems within a week or so. Thanks for the detailed bug reports everyone.
Cheers, Jeff
Pete...
