Last month I wrote a tool called "brr" - eBPF Runtime Reporter and Profiler. It displays a bpftop-like eBPF program summary, but you can also zoom into any program to see its source code lines (if available) and profile the eBPF program activity and any kernel code activity called/caused by the eBPF program for the full picture of where your eBPF program time/latency is going.
I wrote it mostly with Codex for my own use, but just pushed the latest release to GitHub (with screenshots) in case anyone else is interested:
In addition to cycles, I suggest gathering TLB miss rates. eBPF isn't magical and any maps of significant size may pollute your virtual address translation caches. The last time someone asked me to profile eBPF at work, over 90% of the cycle time was attributable to page table walks, and this also had severe collateral impact on the applications.
