Could be a few things:

  * bug 2541 (except latest 3.0 and 3.1 releases)

  * lots of regex patterns

  * garbage collection of the various caches

  * UFS storage system catching up after a period of load

  * memory swapping

  * RAID

  * ... any combination of the above.

If you have the strace tool available you can look inside Squid and see.
  Or a use "squid -k debug" to toggle full debug on/off for a short
period and troll the cache.log afterwards.
