yes, but doing this when mkfs runs might be feasable or perhaps why not tackle a subset of the problem and just optimise swap partitions
not knowing for sure, but are writes stored per disk or per partition and could the ordering of reads/writes be done differenly for say the swap partition as opposed to say an ordinary file system? putting the swap in the middle of the disk might be an option -- simon
