I have a mirror mode got.git repository sitting here that I switched
from stsp_gitolite@git.gameoftrees.org to anonymous@got.gameoftrees.org
a few days ago:

remote "origin" {
        server anonymous@got.gameoftrees.org
        protocol ssh
        repository "/got.git"
        mirror_references yes
}

Fetching performs poorly.  It is very slow and appears to always
download at least ~3 MB of data.  Here's the latest instance:

$ time got fetch

The only upstream change since the previous fetch was the single
commit c3b9af18468be6672f62e2d321b5fc2893837c62.

Is this expected?
