Hi,

Wow, thank you for trying! I'm surprised and honored ;-)

Why do you think it's 85%? Are you expecting more than 894,279 versions? 
How did you count them? I'm sure there's a difference in counting or a 
bug in my code ;-)

You are right, it hits a TODO. But that one certainly is after 
collecting all the CVS versions in blobs. It's just before the toposort, 
when trying to resolve circular deps. As I've told you, blob splitting 
in not implemented, sorry.

And repositories as huge as mozilla's certainly have some dependency 
cycles, thus blobs would have to be split. Which is exactly what's still 
missing. As soon as I have some free time I'll try to implement that 
function.

Did you watch memory consumption? Any idea how much it took? I think I 
can still optimize memory consumption, because I probably use that 
shared_ptr to often. But I'm optimistic, that all the algorithm can run 
in memory on a modern system.

I had the whole mozilla repo lying around one day, but then needed some 
free disk space and deleted it. I now take FreeBSDs cvs repo, which I 
still have around. It's around 3 Gb in size.
