This run also packed tree files together (everything produced by write-tree went into a packed file), but not the commits. I estimate I could save about another 168m by packing the tree files and commits into the same file with the blobs, but this wouldn't make any of the times below faster. git - original (28k commits) packed FS size 2,675,408k 1,723,820k read-tree 24.45s 18.9s checkout-cache 4m30s 3m5s patch time 2h30m 1h55m The format for the packed files could be smarter, such that it didn't require decompressing the whole packed file to read one item. I would guess I could get another 20% checkout-cache performance out of it via more tuning, and probably another 10% of space savings. Of course, none of this is likely to convince you ;) If you decide later on it's worthwhile, I don't think it would be difficult to add then. -chris - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
