Stumbled across this issue, seems we can close it.

ENABLE_PPROF is in the cheat sheet, and as far as I can tell there is no longer a command-line option for it. (Although, I wonder if that would be a good thing to add...)

My apologies, I confused serve with web.

We do not have it documented for serv, though since it's mostly an SSH passthrough, I'm not entirely sure when it gets used off the top of my head.

Gitea serv in combination with PPROF envvars is used to profile the cpu/memory consumption of the SSH passthrough.

I am aware of this, however the serv command is never directly used by a human (that I know of), only by Gitea itself when invoked for SSH.
Given that, the config makes sense, however I'm not sure when the CLI flag would be used in that situation.

The entire serv command is undocumented because it's not a command users are expected to invoke manually.

Frankly if you are wanting to pprof gitea serv you are in way too deep and you should be asking for help. No documentation is going to cover such problems.
