By clicking through some links on the article I found this: http://www.brendangregg.com/blog/2014-10-31/cpi-flame-graphs.html http://www.brendangregg.com/blog/2014-10-31/cpi-flame-graphs... Now I wonder how easy and manual work it would be to do these combined flamegraphs with CPI/IPC information? My cursory search didn't find nary a mention after 2015... Perhaps this is still hard and complicated. To me it seems really useful to know why a function takes so long to work (waiting or calculating) and not "merely" how long it takes. Even if the information is not perfectly reliable nor can't be measured without effect on execution.
