I would not call ~20 u-sec latencies comparable to the pair of D525MW's I
have. They are showing circa 3 u-secs, with a very occasional, separated
by hours, exception that will throw a realtime error. This is at 23 u-sec
BASE_PERIOD. Reseting BASE_PERIOD to 25 u-secs absolutely stops that.
Considering that 25 is 20 better than what I had to start with using the
older xP1600 athlon, I'm ecstatic.
However, since the D525MW is now mostly out of the pipeline, I agree that a
suitable 'next-gen' board needs be found.
However, I am also concerned that we are running out of time with the
10-04.4 LTS distribution, particularly since we seem to be locked into a
kernel whose uptime on this machine has only exceeded 3 weeks of uptime
once in close to a year. Its scheduler for normal desktop usage sucks dead
toads thru soda straws, and it leaks memory, often into swap on a 4 core,
4Gb machine in an hour after the reboot. This morning seems to be an
exception, no swap at 5 hours uptime, but when I rebooted, it took 2
reboots as usual.
I have been tempted to add a 6 hour cycle to the root crontab that does a
swappoff -a, sleeps 2 secs, and re-enables swap.
Has anyone else been tempted to control the leakage by this means?
