An upgrade would do you good.

The greatest factor will usually be network round trip time, so if
this is a one-shot conversion, rsync the repository to somewhere
close and run the import over a local network. I've had some "fun"
trying to import sourceforge svn repositories that were large-ish
but not huge (same seat you're in, basically), but since I get up
to 800ms round trip time from sweden, conversion took forever.

I've seen such tags before. They were added by an automatic build bot
as a marker to say "hey, I just built this".
