You should definitely do this for file systems used for things like
squid and news (Usenet) which are accessed heavily and are not read by
normal users.

Normally UNIX saves the access time in the directory when any file in
that directory is accessed. "noatime", in UNIX versions which support
it, turns that feature off and can save a tremendous number of
directory updates, hence reduce disk writes, hence increase
performance.
