Reduce overhead of polling perf buffers about libbpfgo HOT 3 OPEN

Would be curious to know if this is something you've also experienced in Tracee. It would be fantastic to see if implementing this in Go would help here. I think it would!

This is something we have discussed historically indeed. There was an issue opened in Tracee for moving away from the CGO polling logic and implement that in Go (inside libbpfgo).

Maybe the time has come ? @yanivagman FYI

Yes, indeed we discussed this in the past (#42).
Like I wrote in the other issue, cgo improved in recent versions of go and I didn't see any particular improvement moving to pure go. Yet, I didn't put too much effort into this back then, and it may be a good idea to explore it again if you see a performance impact related to cgo.

FWIW we use Go 1.20
