I haven't measured work on the server, and timing individual clones is
liable to a lot of variation from variable load there, but for a single
clone --mirror of the 1b repository (so all refs, including refs/deleted/)
I got
real 13m16.473s
user 16m45.429s
sys 0m33.901s
and 1360 MB objects directory, but for a clone without --mirror (so only a
limited subset of refs and the server needing to build a pack)
real 15m5.554s
user 12m11.771s
sys 0m26.914s
and 950 MB objects directory. Adding the objects from the existing
git-svn mirror (presumably also under refs not fetched by default)
increases repository size by about 300 MB, based on a previous test of
doing that (most blob and tree objects will be shared between the two
versions of the history, but all the commit objects are separate).

I'll plan to change the author map to default to @gcc.gnu.org and @gnu.org
addresses.
