On a Mac mini M1 8/256 I get only a slight speed increase (15% faster) with the 
arm version (experimental R-devel build).


Speed differences were covered in an earlier report so please look in 
the list archive.  Speeds are really dependent (for both Intel and ARM) 
on the load on the machine and the size of the task: typically the ARM 
version is 40% faster, with a very wide range.




Thanks
