説明

It would be very useful for extension operators and extension writers to see how much time is spent in the extension code (Lua, Wasm, ext_proc), to troubleshoot and root cause excessive latency. At a minimum, the breakdown could be stored per request in a filter state and emitted as an access log. I think there's some code that does this for ext_proc but it needs to be generalized to other extensions.
