You have a 64-bit CPU and a 64-bit OS. Why downgrade? Here are the three most common scenarios:
Just don't expect to run a massive microservices cluster on it. For that, you definitely want 64-bit. 32 bit java runtime environment
Settings that manage how Java interact with the system. Key Technical Limitations You have a 64-bit CPU and a 64-bit OS
If you are running Java on an older single-board computer, a legacy point-of-sale (POS) system, or an industrial controller with only 2GB of RAM, the 64-bit OS isn't an option. The 32-bit JRE has a smaller memory footprint and runs perfectly on constrained hardware. a legacy point-of-sale (POS) system
