Concerned about page fault ratio

I'm concerned about the page fault ratio (pfr) that I'm seeing (Squid
2.2S5, RedHat v6.0 /w kernel 2.2.14).

The full output of "client mgr:info" is below, but here's the short
version:

pfr = Page_faults_with_physical_i/o / Number_of_HTTP_requests_received

0.47 = 9112 / 19368

(The fault and requests numbers above are low due to my having
rebooted recently, but the ratio calculated is representative of what
I've been seeing.)

This ratio is much higher than the examples I see in the Squid FAQ. I
don't any reason for Squid to have to be swapped out. I've got plenty
of RAM for the programs running on this box and the swap partition is
barely used.

Should I be concerned about the page fault ratio or do these numbers
seem OK?

Thank you.
