Hello there!
Is there some command for perf which I haven't found so far, that enables me
to compare two perf.data files?
When I try to improve the performance, I first get a baseline perf.data. Then
I try to optimize and want to compare before/after. It would now be cool if
perf record could only show the difference between before/after, similar to
what VTune is able to do.
Bye
