[hg] Performance issues
With our instance, it takes sometimes more than 60 seconds to push a minor changeset or to pull a really small repo.
Timing can probably be collected more precisely.
Maybe some gunicorn settings tweaks and other things can help here.
We did a debug session with @gracinet which doesn't show a clear problem with CPU bound gunicorns. During that session the capabilities
request was way too long compared to a request to a standard hgweb.
