I looked at it some and couldn't see anything obviously wrong with it, but it wasn't a detailed inspection.

As comparison, I just tar/zipped the Mozilla CVS repo and it is 541MB. The 295MB git pack number does not have commits and trees in it, it is revisions only.

It is not impossible that when the trees and commits are added to the 295MB number that it won't end up being near the 541MB number. We already know xdiff is better at generating diffs than CVS diff. And I still have to add 250K log entries and trees. Those are going to add at least 100MB.

I will get back to work on the import code over the weekend. One of my 2 year olds gave me a cold so I have been useless the last couple of days.
