I still have the ~2 second "glitch", and here's what I've done so far:
- Stopped displaying my xclock (thanks Angus)
- Added the NOINTR directive in my irix.sm (thanks Dr. Colin) as shown
in the FAQ. I now have protected processors 9, 10, and 11 from
broadcast interrupts and lock them in my app.
- I run a "desktop" with three "desks", some with nice picture backgrounds.
Haven't had the chance to disable this, but the desk I run the app on
has no background defined. Also, the framebuffer is 2560x1024 across
2 monitors so I can debug if necessary. (printf's off when testing
framerate, however). Haven't compare it to a 1280x1024 framebuffer
yet.
Now I haven't had a lot of time to test various setups, but here's a
snapshot of "top" when the machine's idle:

Most curious is this sockd, which seems to be running with a rather
high priority and takes up quite of bit of CPU time, too. I got a
little info on sockd, which is a firewall proxy daemon? The NFS
mounts are few and checked to be inactive during testing. Maybe
bdflush?
I do run an intersect process, but the stats show "0" time spent
(and I've disabled the intersect and same prob stays)
Once again, iR, 12CPU, 2-64Mb RM6, 2Gb RAM, IRIX 6.2, Performer 2.1
OK, Round 2 begin!
