Yeah, so... every benchmark is terrible. Is this one worse than most?

I tried benchmarking using:
time factor $[65863223*65863159]
     - but that's division test, not a CPU test, and there are two
     versions of factor floating around
time cat /dev/urandom | head -c 10000000 |  bzip2 -9 - | wc -c
     - but that seems to be memory test, not a CPU test.

Dhrystone seems to be making some kind of comeback in RISC-V land. Is
there something better? Something better that is still reasonably small?

Best regards,
