Way back in my 6502 days I entered a competition for the fastest sieve program. My program had self modifying code running on the zero page. To reset the 8K memory the program employed 24k memory for the store instructions. The winning entry left me in the dust - rather than zeroing the memory in the winning program’s array was initialized with a template of the first few primes. There can be solutions that are even faster than the fastest possible zeroing.
