i386 or amd64 from small Cloud instance ?

Hi,

My Cloud instances are always small (1 ou 2 vCPU, far less than 4GB of
RAM).

From what I saw, all the ports I need are available in i386 and amd64.
Every Cloud provider I checked are using KVM hypervisor.

Regarding OS and ports performance, does it make sense to use i386
rather than amd64 ?
Or is amd64 somehow better even on small configurations ?

Thanks,
Jo
