What problem do you think you're having?

I don't know what you're talking about, so it's hard to answer.  But
polling shouldn't have much to do with paging behaviour.

If you are just asking how to reduce page faults, the answer is to add
memory.  Offhand, that does seem to be a fairly high paging rate.
