Thanks! It's been a bit of a labor of love for quite a while, these are the big three but there are a bunch of other little things.

Like the time I had to optimise map insertion because the linux kernel does some truly insane locking when you use specific types of eBPF maps:

This is slated to be improved (or has already been improved in kernel 6.8?). But for now wag sort of just side steps it in a horribly stateful way.
