L1 and L2 cache

[Nandan gogate]

Hello,

I am in the process of finding out why our software doesnt run as fast
as it runs on solaris. I would like to know on board (processor) cache size for
D class server. model returns me
9000/800/D390

How can I find out how much on board cache my machine has ?

Thanks a lot for your help.

Here is a link to D-Class documentation on HP's web site.

I don't know if you'll find what you need or not, but it is a place to start.

You can use Support tools manager to get the onboard cache of a processor. You can use xstm/cstm commands, if you have STM installed on your server. I have attached the sample output of a xstm which gives cache information, etc
of a processor. For L1 (Primary cache/Inside processor/Instruction Cache), L2 (Secondary cache/between processor and main memory/Data Cache) details have a look at the attachment.

Hope the information provided helps you.

Enjoy !
