Would it be possible to say if this performance is sending or
receiving mail? Either way, show the `delays='' logging, which
reports the time spent in different stages of delivery.
The format of the "delays=a/b/c/d" logging is as follows:
o a = time from message arrival to last active queue entry
o b = time from last active queue entry to connection setup
o c = time in connection setup, including DNS, EHLO and STARTTLS
o d = time in message transmission

I suspect that your mail sending program is too slow. You can test
Postfix raw speed with smtp-source test program, part of the Postfix
source bundle.
