Page Faults

-- [ From: squid * EMC.Ver #2.5.02 ] --

Hi to all.

I am running RedHat 6.1/Squid 2.2 STABLE4 on pII-350 pc, with 256mb ram.
256mb swap and a 7.2gb filesystem just for the webcache.

When checking it with the cache manager, I get on the report a lot of Page
faults with physical i/o, and the value is increasing at a rate of aprox 12-
15 per minute.

Could someone help me with this ?
