On a typical half empty and non-fragmented filesystem, the data is stored on the first part of the hard-disk, when DRBD writes its meta-data at the end of the hard-disk, the head goes through an average longer distance than if it was at the beginning and hence average latency goes down. -- Cyril Bouthors -------------- next part -------------- A non-text attachment was scrubbed...
