scheduler coolness
just comparing notes:
i run 2.4.22 with OpenMOSIX and Win4Lin patches, as well as the 2 latest security patches. For graphics, I use only gdm on the headless server (a P3 667 w/512MB) and a diskless NFS root X terminal thru XDMCP on the clients (anything from celery 433 to P133). After worrying that my apps would knock down the activity of the other users, I thought to nice all my processes and let the masses have whatever Mozilla wants (since that's all they'll be running ;) . The other terminals aren't even setup yet, but I was getting severe sluggishness that made me thirst for GHz.
So after I hung up my terminal many times and watched it lock during heavy user load, being the only user(!), I decided to go ahead and nice everything under gdm. I edited /etc/X11/gdm/Xsession and put a 'nice' in every 'exec somewindowmanager' and now everything is faster. I mean, the local X is far more responsive, windows draw sooner, and apps don't momentarily hang the display... I'm assuming this is due to gdm now having the highest priority in userspace aside from the various daemons, thus less network latency and so on. so all is grand.
any thoughts/comments?
(_besides_ that i'm mad for mixing OpenMOSIX and Win4Lin 8^)
