Hey folks,
I’m at a point with jank where I’m comparing benchmarks against Clojure. I’d very much like to profile these benchmarks to figure out where the time is being spent, but all of my attempts thus far have resulted in mostly [unknown]
frames, rather than anything discernible.
Non-JIT compiled jank frames show up fine, but what I’m looking to profile is largely JIT compiled. So far, I’ve tried:
- Tracy
- Perf + flamegraph
- Callgrind
I’m compiling with -O1 -ggdb3
. If there are any tricks for getting more info in these profiling reports, or if there are different tools you guys are using for root, please do let me know.
Example flamegraph:
Cling: 0.9 release
OS: Arch
Kind regards,
Jeaye
