Typo ... Xorg.
Yes, I've tried several aarch64 versions on the RPi-3 and timed performance against
the 32-bit versions, and the 32-bit versions substantially out-perform the 64-bit. I keep
hoping the 64-bit versions will get faster, but I'm not so sure any more.
Mostly I wanted to do some ARM8 assembler to learn the architecture and test some
algorithms that I hoped would leverage ARM8's architecture to improve performance.
The excursions into 64-bit SUSE and Fedora are educational diversions, as I try to find a
64-bit version that is stable and performs reasonably well as an OS platform for my
testing. So far, I've spent more time on my diversions than on my algorithms. :-)
