I was looking into this recently for a different reason.  At first I
thought we were missing a few fflush() calls, but I narrowed things
down to print_commit() in got/got.c -- where building up the string to
output is the thing which slows us down.  There'll be something in
that function slowing us down.  Maybe got_object_commit_get_logmsg()
-- but I've not had time to really dig into this.

Kindly,
Thomas
