FWIW, Wireshark 4.6.0 ships with `sharkd`, which encapsulates all the EPAN dissectors into a simple to use server that accepts JSON-RPC requests.

It is quite easy to write specialized performance tools on top of `sharkd`, and since it has the entire power of the EPAN (including statistics, charts etc.), using `sharkd` is significantly more effective than reading straight from libpcap.
