Slow cleanup(8) processing or disk I/O contention. Another
possibility is a syslog daemon configured to do synchronous writes
for every log entry (stresses the disk and slows down syslog clients
such as pickup).
Look for excessive header/body checks, or overly verbose logging.

The qshape program does not support maildrop queue files.

Make sure logs are not written synchronously and the local socket
(/dev/log) is a datadgram not a stream socket.
Finally, SMTP submission (at modest concurrency, typically ~10
parallel connections are about optimal) is much more performant
that submission via sendmail(1).
