Hi John,
Thanks to the needling by the Sun folks :-) we were reminded that we had
never gotten around to submitting the 350 MHz results for the
AlphaServer 8400 5/350, which runs its bus faster when you increase the
clock rate for the CPUs.
These runs were done by Zarka Cvetanovic, of server engineering in
Maynard. You may remember her as one of the enthusiastic questioners
after your visit.
We look forward to seeing these results appear on your web page.
Thanks!
