You are confusing "we", "I" and "you" again. .... Yes, I (and I'm guessing everyone else who have thought about it for more than say 5 seconds) agree that having rsync remember the file tree to save the disk IO for each sync sounds like an "obvious solution". But reality is more complicated. If it was such an obviously good solution someone would have done it by now. (For starters play this question: "What is the kernel cache?"). Andreas' solution is much more sensible -- and as have been pointed out before we DO USE THAT; but the problem here is not with clients who are interested enough to do something special and dedicate resources to their CPAN mirroring. - askThread Previous | Thread Next
