Thank you for an answer. i did what you told but for some reason tracing process just hangs out. ❯ xctrace record --template 'Preconfigured CPU Counters' --launch -- ./target/release/deps/flower-8140bd4c6b5d1486 Starting recording with the Preconfigured CPU Counters template. Launching process: flower-8140bd4c6b5d1486. ... nothing happened here for more than 20 minutes since I ran it OTOH running it normally finishes almost immediately: ❯ time ./target/release/deps/flower-8140bd4c6b5d1486 ./target/release/deps/flower-8140bd4c6b5d1486 0.02s user 0.01s system 130% cpu 0.023 total Can I do anything to make trace end with results here?
