Is this basically like Valgrind, but using CPU counters?

Think like callgrind, but without the overhead.

The true x86 equivalent is probably `vtune`

For open source there's `perf` + `flamegraph` but that's not interactive, or `KDAB/hotspot` which is probably the closest open-source thing to Apple Instruments.
