I don't know much about anvil, but the first thing I'd look at if the
system is slow is "uptime" and "vmstat 5" commands to see what the system
is doing.  Is the load high?  Is it swapping?  What is the system doing?
The two commands above answer all those questions and more.

I would guess you're a bit light on RAM and the system is swapping.
SpamAssassin in particular can take a lot of RAM.

It means that the system found an account with both local delivery and
forwarding enabled.  It will try to follow forwards that are set up, so if
you create an account "a" that forwards to "b", it will use spam settings
for "b", allowing you to centrally manage spam settings for a heavily
forwarded set of accounts.  However, if you forward *AND* do local
delivery, it has to stop this redirection and do a real delivery to the
local account *AND* inject another message to the destination.

It's an internal log message.

Thanks,
