You want noatime there..

As I said I am not sure if UFS logging will help performancewise. The
Disksuide logging will if a separate disk is used for the log (the same
log may be shared by many filesystems).

Squid (as most other software) does not use atime for anything. It is
almost a pure waste of resources.
