Subject: Speed up git-svn fetch
Date: Wed, 23 Apr 2008 15:17:42 -0400 [thread overview]
Message-ID: <1208978273-98146-1-git-send-email-aroben@apple.com> (raw)
I first sent this patch series 6 months ago today [1], then resent it after
some comments from Junio, Johannes, and Brian [2]. Here it is again, addressing
further comments from Junio and Eric.
The point of the series is to speed up git-svn fetch on Cygwin, where forking
is quite slow. In my informal testing, this patch seems to speed things up by
~1.4-~1.7x. We accomplish this by having a single long-lived git-cat-file
process and a single long-lived git-hash-object process for the duration of the
git-svn invocation.
This series is based on top of next.
-Adam
