Hello all, I just thought I'd give internal bitmaps a try using mdadm -G -b internal and the write speed: dd if=/dev/zero of=test.dat oflag=dsync bs=1024k count=1024 went from 20mbps to 15mbps. Is that a typical hit for the bitmap? I don't resync very often so it may not be necessary. Just wondering whether there is anything that should be tuned. raid5 5x sata 320gb drives on ahci ncq enabled.
