Hi Boris,
I haven't had an opportunity to work with any AMD64 hardware yet,
but have had good results with 5.4.? on i686. 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.

I hope this helps!
