filtering on git fetch?

Hi

Setup

(*) I'm fetching across a transatlantic link (RTT in the 300ms range on a good day) (*) I'm fetching from a gerrit server

$ GIT_PACKET_TRACE=true git fetch

shows tons and tons of

09:39:43.355675 pkt-line.c:80 packet: fetch< 3a7ad7ee5d7daa0c93a80fbb32a677597d81ac75 refs/changes/00/9000/3 09:39:43.355684 pkt-line.c:80 packet: fetch< 6cacf1db5311f6b250ebaa12c71419a8ff9b747e refs/changes/00/9000/meta 09:39:43.355693 pkt-line.c:80 packet: fetch< 849a43434a5ede9ce9b70da14231f34edb2593fb refs/changes/00/90100/1

type stuff before it starts fetching the updates to master that I am interested in.

Is there any way to tell the remote git server that I'm only interested in a subset of stuff?

Thanks, Noel Grandin
