hello,

the original message is:

>Dear all,

>I got a brand new DEC ALPHA DS10 ( proc 21264A at 600 Mhz and 1GB RAM,
>Tru64 UNIX v5.1). We run FLUENT a commercial code for solving fluid

>at 800MHz (128 MB RAM - Windows 2000).
>In both cases, Fluent is the only soft running and we use internal disk

>I guess that (memory) configuration of the ALPHA might be set unwell,

>PIII- 1GHz) the ALPHA station should be much more faster than the Pentium.

>Thanks for your help.


the answer is:

If you have not tuned the kernel, I would suggest running sys_check and note
the tuning suggestions there.

As root:

# sys_check > /tmp/hostname.html

thank very much to:
