Scripts for performance tuning ?

[TSch]

Hi folks,

any idea where I might find a script or something for automatic performance tuning?

Something that automatically changes certain values (vmtune, etc.) and reports the effects ....

Thanks in advance !

Hi,

I used the following one to fine tune some vmtune and schedtune values.
=========================================================
#!/bin/ksh
#The scripts runs the performance benchmark,while changing vmtune and other parameters,one at a time.It prints the vmtune params and the related benchmarks results into a log file.
#It activates the “benchmark1” as a main benchmark – it can be any given benchmark
#Default vmtune values loaded on boot:
#/usr/samples/kernel/vmtune -p 10 -P 30 -c 1 -R 64 -f 120 -F 184"
