Increase the performance

[bond007]

Hi All,

Could you give me the tips to increase the system performance, in terms of memory /IO and other resource management ?

Thanks in advance

Hi Bond,

Several threads are available in ITRC regrading this topic, you can take a look at

My rule of thumb:

1) swap = 2 x physical memory minimum
2) mirror everything on root disks across controllers
3) mirror swap across controllers
4) spread your I/O across as many SCSI or FC controllers as possible.
5) investigate PRSET to guarantee processing resources for apps if your server has a CPU bottleneck

Dear Bond,

You can also distribute the disks on diff controllers and incase of mirrors it would help you interms of redundancy also.

With Regards,

Siva.

and also it is mandatory to tune the kernel parameters to the APPLICATIONS requirement
