Well, for good performance one should not have much of a queue at all,
the mail should go out as quickly as it comes in. If you're queueing
a lot of email, then your output is not keeping up with the input.
Unless there's a particularly good reason why you believe that OpenSMTPD
would do better than Postfix in bulk mail delivery performance, it is not
helpful to recommend it here.
