It doesn't seem to be obvious where the problem lies, and I do not have
access to ARM-powered Mac hardware (nor any Mac hardware for that matter)
so I am unable to debug this. Anyone else?

What happens if you run 'make clean all' instead of just 'make'?

Ok, so the latest being slower on both builds at level 8 than the Released
1.3.4 makes sense with recent compression improvements. Thanks. I was using
level 8 for all tests.
As for the Neon optimizations, it seems that if I configure for Universal
binary ( -arch arm64 -arch x86_64),the neon

It seems for some reason NEON is not enabled by configure. Can you
provide the config.log file so I can check what goes wrong?

Huh, I have no clue why my mailing program decided replies to this

Martijn filled me in that recent changes (since the official 1.3.4 source)
have added ARM improvements, and that if I get the most recent code, I

I suppose)
Thanks,

You raise excellent questions. I have not been paying attention to Apple's
compiler support for the M1, M1 Pro, and M1 Max.
Do you have the latest compiler from Apple?
Are you sure that -O3 is the best option? I seem to recall that the 'best' has

I also recall that
