I confirm oprofile (0.96 on my fedora 14) works just fine (see below).

Do you recommend me to use the latest (git) version ? 0.96 is quite old (2011)

Only if the version you're using doesn't work.

Could you explain me a bit how to get sample counts corresponding to the complete benchmark (few minutes long) ?

I don't understand. As far as I can see that is what you have.

should I use the event argument to set the highest count (reset) value ?

By default, oprofile uses: CPUCLKUNHALTED:100000:0:1:1 opcontrol --event=CPUCLKUNHALTED:400000 What is the maximum value I can set ?

I always use the default. The more you increase sample frequency the more overhead there is.

The real test is to experiment and see if it makes any difference.

Andrew.
