I suspect it is slow because is reads / writes in pcfs "cluster" size units. This can be seen in "iostat -xnzc 5" output; divide the kilobyte/s value by the ops/s any you'll get the pcfs' cluster size. > The same operation on a Linux or WinXP machine can be a lot faster. I suspect both optimize the case where adjacent clusters are accessed and perform i/o in bigger chunks. > There was a bug logged against this, but I don't know > if it's going to ever be fixed.
