I feel like scapy is a bit of a special case though. It's unusually dynamic because it allows kind of arbitrarily crazy things. I feel like it's maily best for prototyping. I've had 1000x speedups (100s of milliseconds to dozens of microseconds) just by removing dynamism. In our case we used scapy to work out the packet shapes we cared about and then just implemented just that subset (still in Python!). But that dynamism really helped with the early stages along with wireshark
