Comparison between Raspian 12 Bookworm on Raspberry Pi 4 and Raspberry Pi 5

My idea was to compare the performance of the Raspbian Bookworm (and not the Debian) on Pi4 and Pi5....

The results are definitely surprising     [code][code]Regarding this...  is it understood why the latency was so much better in the RPi 5 test, than the RPi 4?  Is this purely a result of improved processor performance, or is there some other underlying reason?  (And, has that result been reproduced?) Unless I'm misunderstanding, I think that latency is quite a bit better than I currently get on my 10 y.o. AMD PC, which implies I could potentially replace it (and its parallel port) directly with an RPi 5 and its gpio pins.  Which I confess excites me a bit.  :-) paul

ITs difficult for users to compare the products until they have a robust installation method for the pi5. But it has been reported latency is much improved.
