Nice. If the command runs more than 5 minutes, it may worth to add running time.

I don't know if it is possible to measure bottlenecks for child processes, but if all commands are competing for disk I/O or memory, because they are being run in parallel, it may be worth to warn about that too, to optimize the times needed to run these hooks in future.

Good suggestion. Although it requires some statistics gathering, because we need to understand what is too much time/memory and what is not.

Also limiting the concurrency is a thing to consider. I am welcome for new suggestions, please, come and create some issue :)

Or you can start a discussion instead: https://github.com/evilmartians/lefthook/discussions, and we can continue it there. This is a good point for a discussion, especially for such a big projects like GitLab.

Thanks. Not this week, but next time I run into this, sure, I'll make a thread.
