Ok, this is the original dd command of savepart script, but with bs=1m:
dd if=/dev/${disk}d bs=1m count=$size skip=$offset \
| gzip -9 \
| progress dd of=$file
running the script this way gave me a transfer rate about 800kbs...and
changing the gzip option to 1 didn't make it any better...
so, i tried to remove gzip command to see if the problem was compressing
...this is the command:
dd if=/dev/${disk}d bs=1m count=$size skip=$offset \
| progress dd of=$file
running it on netbsd gives me a transfer rate of ~5MBs:
$ sh savepart wd0 e image
but if i boot g4u kernel, and try to make write this file in the fat
partition the transfer rate stands around 1MBs, this is the script:
$ mkdir /mnt/fat
$ mount /dev/wd0f
$ savepart wd0 e /mnt/fat/image
I guess it's it.
