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

No. I have multiple 32-bit systems, one of which is Intel.

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. 
   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. 

That's not at all what I was asking or talking about.
