Maybe easier than trying to guess > at the answer. I have not yet tried to bisect it, but that?s the next step on my todo list*. The mbuf patch was just an educated guess to start a discussion. I hoped that I was just doing something obvious wrong, and/or that someone could point me to performance regression tests that were executed to proof that the mbuf patch does not affect performance. However, there don?t seem to be any 'official? performance regression tests, are there? Paul * I probably won?t be able to it until next week, though as I have to to finish the paper about my packet generator
