Netflix has announced
the release of a tool called bpftop to help with the performance
optimization of BPF programs in the kernel:

bpftop provides a dynamic real-time view of running eBPF
programs. It displays the average execution runtime, events per
second, and estimated total CPU % for each program. This tool
minimizes overhead by enabling performance statistics only while it
is active.
