It will help a little; e2fsck -D compresses the logical view of the directory, but it doesn't optimize the physical layout on disk at all, and of course, it won't help with the lack of readahead logic. It's possible to improve how e2fsck -D works, at the moment, it's not trying to make the directory be contiguous on disk. What it should probably do is to pull a list of all of the blocks used by the directory, sort them, and then try to see if it can improve on the list by allocating some new blocks that would make the directory more contiguous on disk. I suspect any improvements that would be seen by doing this would be second order effects at most, though. - Ted - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
