Subject: svn to git, N-squared?
Date: Sun, 11 Jun 2006 22:02:18 -0400 [thread overview]
Message-ID: <9e4733910606111902l709c71ccyf45070d55112739e@mail.gmail.com> (raw)
I have Mozilla CVS in a SVN repository. I've been using git-svnimport
to import it. This time I am letting it run to completion; but the
import has been running for four days now and it is only up to 2004.
The import task is stable at 570MB and it is using about 50% of my
CPU. It is constantly spawning off git write-tree, read-tree,
hash-object, update-index. It is not doing excessive disk activity.
The import seems to be getting n-squared slower. It is still making
forward progress but the progress seems to be getting slower and
slower.
It looks like it is doing write-tree, read-tree, hash-object,
update-index once or more per change set. If these commands are
n-proportional and they are getting run n times, then this is a
n-squared process. Projecting this out, the import may take 10 days or
more to completely finish.
