Bitcoin Core 32.0rc2 is running on the Pi5 (Jennings). There was work in this version (not in the current release which I previously ran) to "prefetch" utxos for the one block currently being validated, using a persistent threadpool that grabs from LevelDB utxos that would be a cache miss upon validation hitting the utxo store. This has been advertised as a significant performance increase, which I don't think will hold up.
