That approach may be reasonable for many arm architectures which do not show considerably lower performance on 64 bit compared to 32 bit. For the Pi4 this is an undeniably good reason not to use 64 bit because contrary to common believes the 32 bit kernel has no problems with 8 GB of RAM. Regards LinAdmin > > Best regards, Ryutaroh >
