I do realize that my first post was out of line and I apologized to Bill off-list. I just thought that: A: With such a lack of important details in the first post, blaming the problem on the FreeBSD version was a bit pre-mature, and B: Even with the speed issues in 5.2.1, 50% is quite a large difference, so I thought it was likely that there was something else going on, but of course, like you said, we would need more information to determine what. Also, the original poster should definitely be using 5.3 instead for this thing. -Josh
