I can relate to your frustration, but can say that I was able to greatly improve 5.x performance with some effort. For example I went from a maximum sustained disk write of 15Mb/s to 90Mb/s on a file server. That said, to help you get a better response to your question I would suggest trying these things: - Document and post your testing procedures and results. This will allow others to get a much clearer picture of what may be happening. As I'm sure you know support via e-mail is very difficult because there is so much information that is missing. - You may want to try the performance list if you don't get any answers from this list. - File a problem report so that the developers are aware of your situation. I don't think that they spend allot of time on this list.
