While searching on the net about Perf I found in some articles, that recent developments in the Linux aim to solve problems found in Oprofile.
I would like to know witch problems are in Oprofile? and the difference between perf and oprofile.
I know that both perf and oprofile are profiling tools for hardware events. We can either use perf or Oprofile?
Does perf replace Oprofile? Or they have both different features?
