It's been running for about 20 hours on 2.5.34-mm1.
A few observations:
The swap happy processes from hint _really_ slowed
down when they hit swap. swap is on two scsi spindles
shared with standard filesystems. It seems they are
being penalized a lot for being swap hogs, though it
could be just that the swap devices are slow. Hint
may be abnormal in that it really accesses all the
processes memory space. (I'd prefer a combination
of a big process that uses a lot of mem, and other
processes that are big but relatively inactive so
they get paged out.)
I don't have any other systems to compare the
current run to.
I expect the hint processes to run until either swap
is full, or they hit the ~3gb limit. At the current
rate it may be a day or two.
So I'm wondering if you think i should just abort the
current test, and try 2.5.36-mm1, or if the benchmark
needs adjustment.
netperf early in the run had a mostly "low confidence"
intervals. i.e. confidence < 60%. In the later runs,
now that swap is heavily utilized, confidence is high.

I'm not running chat. I may add that if I can teach it
to throttle sensibly.
I was surprised that early in the run, swap was ~ 300MB
used, though the hint processes were ~500 megs. I.E.
Swap was seeing some action earlier than I expected.
postmark creates ~65 gb of stuff. It uses a lun that
isn't shared with swap.
The ed compile loop is very fast.
This is a bit of top. High system time here.

Here is some vmstat 30: cs is high. Oddly si/so bi/bo and in are 0.
That's with either procps-2.5.34-mm1 or rml's recent procps.

Should the bench be adjusted, or should I boot 2.5.36-mm1?
