Here's a mailing today with the virus scanner disabled.  Doesn't seem to be a difference, right?  I attached a screenshot of the disk I/O as well.

Does L-Soft have some kind of paid service where they can help me find the bottleneck, or should I look to Microsoft?

Thanks!

No, it isn't.  It's accepting the RCPT TO lines fast enough, but once you send the DATA and the SMTP server has to actually queue the message, there's a five-second delay:

Again, I would check for things like disk I/O wait and AV/spam scanning delays.  It's probably either slow writing to disk or slow scanning message content.  You can't push mail into the SMTP relay faster than it will accept and queue it.
