Ok. But so can I take it you have confirmed that the machine *is* in
fact swapping during these ParNew:s? I guess so since you mention it
helps to move to standard disk mode
Hi Pete,
I set the swappiness to 0 but the problem remained. The only way I've
managed to avoid it is to use standard disk mode.

As promised on IIRC we also have collected some information as we are
seeing (probably) the same problem.

I'm seeing lots of ParNew messages which is affected performance,
along the lines of:
