The best software is the one, where you can't decide if something is a cool or a terribly ugly idea.

#linux, #ftrace but in userspace, #flamegraphs

Brendan Gregg does some great talks. Just watched this one on #eBPF and #flamegraphs: https://www.youtube.com/watch?v=HKQR7wVapgk

Could understand about half but very interesting nonetheless

@richardstartin Perhaps it’s just me but I find #flamegraphs less useful as the profile grows in size and dominating effects weaken. Then it’s back to #JMC tabular data (usually itable stubs!) which I combine with a little #LogCompilation parser to get the JIT’s view on what’s happening.
