Reading what I wrote might help you a little.

I said "Solaris has the *reputation* for handling multicore better."

I'm sure I could if I was an Oracle marketing rep, but I really don't care.
I use Linux, Solaris, and 3 different BSD and they all have their good
and bad points. YMMV.

I didn't bother to look at your link but if you don't like what I wrote,
think of the value of comparing whatever OS you are talking about running
on *Itanium* to running it on x86. That's not exactly a sound basis for
comparison :rolleyes:

I was suggesting to the OP it might be good to try a different OS on *his*
hardware if he has a nice box and isn't happy with the performance. I don't
see the crime in that and sorry some of you found it so offensive.

Maybe you  should just buy him an Itanium farm if you feel so strongly
about it ;-)

Have a nice day.
