> - performance (why is it slow? why does it allocate this much?)

One of the pieces of fleet-wide tooling that heavily uses eBPF is PyPerf, which we talked about publicly at Systems@Scale in September ("Service Efficiency at Instagram Scale" - https://atscaleconference.com/events/systems-scale-2/ - video also coming soon, I think).

Is there any public code for these perf tools?
