The ref advertisement in the v0 protocol is unconditional and always complete. In v2, the client is able to specify which parts of the namespace it cares about. Try: GIT_TRACE_PACKET=1 git -c protocol.version=2 This will probably be the default in v2.28 (it was the default in v2.26, but there was a performance regression, so we backed it out for v2.27). -Peff
