This is an OS configuration/tuning problem, not an rsync problem.
Application-level code (such as rsync) does not directly deal with
NUMA features such as external RAM banks. Support for that sort of
thing would normally be provided by the OS memory management and
filesystem code -- but (depending on the hardware details) it might
need configuration or even a specialized driver.
