[mythtv-users] How to boost niceness of both front and backends?

[William]

My myth machine also serves are my mail filter and I have noticed that when
fetchmail receives mail it causes livetv to pause briefly. Is there a way to
boost the niceness of both the front and backends? Or to make
fetchmail/spamassassin/clamav behave better on disk i/o? I am running FC2
with a pair of drives in lvm mode formatted with xfs.

Thanks in advance.
