2000 server and CPU usage

Yacine · Thu Mar 22, 2007 3:26 pm

Hi,

A customer have reported 100% cpu usage on a bi-xeon box running StarPort and a SR1520 equipement during multiple copy.

Do you have any feedback on StarPort and windows cpu usage ?
Any tunning to decrease or avoid this type os issue ?
From your point of view could it be due to Windows version ? I mean same test on Windows 2003 R2 will or should not have the same results (incredible cpu usage) ?

Thank you
Regards,

You did not provide any technical info so I guess nobody can answer your question here. Please issue us with 1) hardware configuration 2) OS version 3) StarPort version. We really need to have all this data to proceed.

Of course it's not normal...

Of course (will provide these details asap) but it was just a general question first

Dual Xeon machine is expected to do wire speed with 30-40% of the total CPU time. Anything more is a problem.

Yes, please issue us with some of the details.

P.S. And there should be no difference for Windows versions.
