I have two The Bats! on two computers. One is 2.11 and second one is 4.2. They both use the same account and are configured the same way. The Bat 4.2 sends emails much slower, 2.11 does it almost immediately. The Bat 4.2 starts to send after over 10 seconds, is there any explanation?
P.S Both computers work on XP, and the one with 4.2 is even more powerful, connection is the same.
