 You leave much to guess, such as squid version, os , os -version,
 machine ,machine - type, disk ,memory; all of these playing a role
 in this discussion.

 The 'simple page faults' are not necessarily related to squid's
 algortyhmic problems or issues.
 Just to low phys. mem can cause this, it should not necessarily be
relatd
 to high level application issues.

 Not probably,depends on which network the machine is.
 I don't think that a squid box could generate collisions if it would
 be alone on a network.
