thrashing?

that usually means that a process uses too much memory, thus causing the
system to spend too much time swapping to be able to do anything useful.

have you checked the process size during normal operations?  is it stable, or
does it grow a little all the time?

if the problem is thrashing, I'm not sure I see how that would help.
