I use my RPi4 as my main computer at home. I guess most of the time is used in chromium and I find that websites can be a little slow to open at times. Overclocking the Pi to 2GHz seemed to help a bit. Of course there is a limit to how snappy or responsive one can expect a RPi 4 to be. But I was wondering if a 64-bit OS would help as well. I must confess that I don't know enough about computing to know what situations 64-bit is faster than 32-bit. I know the Raspberry Pi foundation has spent a lot of time optimising Raspbian to Raspberry Pi's, but I figured that at some point their 32-bit OS wouldn't be able to compete with a 64-bit OS.
