Profile. Don't speculate. Your experience with serial mailers does not
apply to programs handling several jobs at once.

In a test at the high end---sending a message to 10 recipients at AOL---
parallel connections were nearly twice as fast as a serial connection.

In a test at the low end---sending a message to 10 recipients at a
poorly connected host in Taiwan---parallel connections all succeeded
within two days. With serial connections, the mail NEVER GOT THROUGH.
