Anyone running OpenBSD/i386 on a 64-bit capable system with more than 3GB of RAM installed should perceive an immediate performance benefit if they are memory-constrained and do any swapping, because i386 is limited to 3GB of usable RAM.
Other benefits I can think of at the moment: a) The increased number of registers available to the instruction set may reduce the number of machine instructions required to complete any compute procedure. b) The expanded size of the registers may offer the same instruction-reduction advantage. c) The doubled internal data bandwidth for memory movement should also result in improved performance.
