If fact, your system may be underutilized. If you have 50% unused memory, you might increase the number of amavisd-new process ($max_servers and complimentary maxproc for the smtp-amavis transport). I would try to get closer to 75% unused memory. I think this would improve throughput. What is your $max_servers at now? How much memory does a typical amavisd process use? If you were running at 50MB per process, and you had 400MB to play with, I would increase the number by 4 or 5, wait a while (maybe an hour), and see where you are at again.
