Any (dis)advantages in HyperThreading? We're running a fairly busy (72k
msg/day) dual Xeon 2.4 2GB RAM with HT on RH9 / MS 4-26.7 / SA 2.63 /
Clam 0.65

In top the MailScanner process continuously has near 100% of CPU 2. The
idle percentage hunts around between one of the virtual CPU's at near 0%
and the rest roughly equal. Sometimes all four are roughly equal. Our
CPU utilisation as showing in Mailscanner-MRTG (older version) is higher
than we would like it to be.

Most of our dual xeon boxes are running with 2G RAM, leaves plenty for a
nice tmpfs. So yes, 2G sounds fine to me.
