Bit of background:
I have a pi 3 running latest beta of Leia, on stretch.
I also have a pi 2 running latest release Raspbian stretch.
Both Pis both boot from identical 16 GB USB3 sticks, and are powered by iPad 2.5amp PSUs.
The problem, I’ve adapted a script which will backup the pis on the fly, one command used in the script is DD, to create a zero filled image of the appropriate size to the users home directory.
On the Pi2 running Raspbian the DD command averages about 12-15MB/s, around what id expect.
On the Pi3 running OSMC the DD command is noticeably slower, around 1.5-3MB/s, it seems to take forever.
I stop Kodi while running the script, and any other services that could be slowing things down but it makes no difference.
Is there anything obvious that could be causing this difference in speed that I’ve overlooked?..if anything id presume the Pi3 would be a little bit quicker if anything.
