Make sure that $max_servers matches the number of queue runners.
This number should not be beyond what machine can cope with.

Both solutions are good. MTA load is mostly I/O, SA load is
pretty much CPU-heavy, so having both on the same host is
a reasonable approach if the platform can cope with it.
If you need to distribute load, a good first step is
to move amavisd-new to a dedicated machine.

I would put MTA-RX and MTA-TX on the same host, mostly for
management reasons. Consider 'upgrading' to Postfix, which
is better understood and better supported (XFORWARD feature
to select policy banks) with amavisd-new.
