I guess all of your hardwares are 64bit. You setup different OS on them.

It's not about performance of hardware. It is about some limitation of 32bit.
2 examples for it:
   1. if we use 32bit value for time, it will overflow in 2038, then
your time will be shown as 1900.
       https://en.wikipedia.org/wiki/Year_2038_problem
   2. A single process (or maybe APP, not precisely), can only use UP
to 4GiB RAM.
       In fact on most system the value is less than 4GiB:
          on intel32, it is 3GiB
          on mips32, it is 2GiB
       But currently, it is not enough, for example, when we build a
big APP, it will need much more RAM.
       The RAM does install in your Rack, but you can NOT use it.

If you are really need 32bit system. Maybe you can say out why you
*REALLY* need it.
For most users, the suggestion is: upgrade to 64bit.
