Wow, what a difference. I got ~exactly the same for RaspiOS 32-bit but
my Ubuntu 20.10 Desktop 64-bit seems consistently a little slower at
around 7.885s. Not doing anything else so I can't imagine it's
background tasks. Perhaps slightly different libraries or compiler
settings for factor? (checking) Well, the slower one on Ubuntu seems to
be newer at least, at version 8.32 vs. 8.30, ha!
