Yes, sorry, all the world's an x86 :( Could you please send me whatever
diffs were needed to get it all going?
I am just preparing that mail :-)
I thought you were running a 256MB machine? Two seconds for 400 megs of
swapout? What's up?
Roughly 400 MB of swapout. And two seconds isn't that bad ;-)
An ouch-per-second sounds reasonable. It could simply be that the CPUs
were off running other tasks - those timeout are less than scheduling
quanta.
I don't understand why an ouch-per-second is reasonable. The mempig is
the only process that runs on the machine and the blk_congestion_wait
uses HZ/10 as timeout value. I'd expect about 100 ouches for the 10
seconds the test runs.
The 4x performance difference remains not understood.
