Real Expectations..

[David Vosburgh]

We have MailScanner/SA/Sophos on a Sun 220R running Solaris 8 with
2x450Mhz and 1GB RAM.  Prior to the Sobig-f outbreak two weeks ago the
system was comfortably handling about 20-25k messages per day with an
infection rate < 1%. The load average was generally between 1 and 2. In
the last few days, we have been getting 30-40k messages per day, with an
infection rate of about 20%.  While the delivery times haven't changed
much (still ~3 to 6 seconds), the load average on the system is
generally between 3 and 5 now.  I think we're getting close to the
capacity of this system at the current load.
