It's not that there's nothing you can do, it's more that it's much, much too early to say what might be improved. A mail server (in any of its incarnations) is a complicated piece of software (usually even several complicated pieces of software) that does many things, uses many system resources in many different ways at different times. The advice to turn to the Exim mailing lists is good in that the people there might be a bit more knowledgeable about this specific situation - they'll probably know, for each stages of the e-mail "travel" process, which system resources are used and how it may be improved. They might also know how to figure out which stage is the best target for speeding up, etc. Once you have this information, even if they are not very proficient with FreeBSD and they cannot help you with the specifics, *then* you may come back and people here will let you know how to enhance the performance for that particular resource usage pattern.
