Help testing it is appreciated: , took a while as there were some problems with 32-bit arches and with elfutils 0.178, all hopefully fixed.

For this specific case and a reasonable number of events, I think the TUI can cope, but yeah, having a nice GUI should be an option, it's a pity the GTK one fell into disrepair :-/

Yeah, that's a limitation to fix, callgraphs are kept separately, only the first is shown afaik, that needs to be fixed, both should be shown somehow, even switching the main criteria should be possible....

Also for labels, TUI screen space is limited, there's a description of what was recorded at the top that can serve as column descriptions, I think?

You can use: perf record -e '{cycles,instructions}:P' perf report And get a group view, i.e. two columns, one for each counter, i/c like in 'perf stat' isn't there yet, but should, at the bucketization criteria used :-/

If you build network equipment and software, you should play attention. Sometimes the algorithms are useful in general software contexts as well.
