solaris performance

Dear all,

I have a solaris 10 server , which is running web applications and webspere also is available.

All the parameters like Virtual memory , swap , hard disk space and Cpu utilisation and I/o statistics are good , but still the server is slow.

It has 2 processores and 128 VPs.

I have a doubt in kernel parameters ..pl find below

* Begin Stack protection
set noexec_user_stack=1
set noexec_user_stack_log=1
* End Stack protection
* Begin MDD root info (do not edit)
* End MDD root info (do not edit)
set c2audit:audit_load = 1
* *** Increase file descriptor per process soft and hard limit - start
set rlim_fd_cur=2048
set rlim_fd_max=65536
* *** Increase file descriptor per process soft and hard limit - end

Pl let me know if the ABOVE KERNEL PArameters are enough OR I have to add more things.

Thanks and Rgds

from your description i think it is a T series server? what do you mean with "slow"? what are you doing and how do you compare?

The MDD root setting is for SVM, you must be having root mirror configuration and it is essential for that, rest appear to be settings required by an application.

The kernel parameters are set as per the requirements of individual applications which are to run on a server.

You need to check the pre requisites of the application, what settings it needs and accordingly tune them.

DukeNuke2 is spot on. You need to explain carefully why things are "slow".

Changing kernel parms is NOT usually the answer, it may in fact make things worse. We can give you some help if you give us something precise to work on.
