VERY BIG "PAGE FAULT WITH PHYSICAL I/O"

Hello,
 
        I've have been running Squid 2.1 Patch2 on my Redhat Linux 5.2 for two days
now. My question is on the cache manage info, the value of the page fault with phy-
sical i/o is so big that it is more than half the value of the HTTP connections.
 
        Is my system swapping with this kind of info. Pleas advise!
BTW, my system is Pentium II 300 with 256 MB ram, cache_mem is at 20 MB
and Cache_swap is at 4 GB.
 
         Thanks.
