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. -- Please use reply-all for most replies to avoid omitting the mailing list.
