Speed of conversion from Subversion repository to Git

Hello,

I am trying to convert the YaST Subversion repository into a Git variant on my system. Unfortunately, a command like "svn2git
http://svn.opensuse.org/svn/yast/" does not finish this attempt after 1,5 days (> 715:13.24 CPU time) here. I would appreciate suggestions for improvements of the execution speed.
(Renicing of the process "git-svn" does not help to increase its processor utilisation in noticeable ways.)

Regards,
Markus

Hello,

The execution of the command "svn2git http://svn.opensuse.org/svn/yast/" was finished today somewhere during the night. I used the version 1.3.1 together with Git 1.6.6.1 on my openSUSE 11.2 system. Now I hope that my conversion try was really successful.

The network activity was mostly low during this lengthy process. Are more software developers interested to speed this procedure up? Do know ways to improve the processor utilisation so that such a data import will be completed faster?

We're in the process of converting to Git at work, and I've found that svn-all-fast-export was the best option for us. git-svn's behavior of a branch's entire history every time it found a new branch (even though it has already seen 3/4 of the revisions involved) caused it to be far too slow for our needs. Admittedly, this was ~1 year ago that I tried git-svn to do a test conversion, and things might have improved since then.

svn-all-fast-export does require access to the raw repository, instead of just (http|svn|svn+ssh):// access, but it does allow you to split out one SVN "repository" into multiple Git repositories in one go.

Hello,

Are there any chances to increase the processor utilisation in noticeable ways by multi-threaded programming?

Do any conversion tasks exist which would benefit from parallel processing?
