Further Investigating The Raspberry Pi 32-bit vs. 64-bit Performance

Finally released earlier this month was the first official 64-bit build of Raspberry Pi OS, the official Debian-based operating system of the low-cost Raspberry Pi single board computers. Following that I posted some Raspberry Pi 32-bit vs. 64-bit benchmarks. Given that generated a fair amount of interest and also some open questions, here is round two of looking at the Raspberry Pi 32-bit vs. 64-bit performance including its impact on memory usage and thermals.
