I tried to read what was said about NUMA Nodes, but I didn't get it. Does it just mean that the RAM Drive is located all in one area on the RAM drive so it will work faster?

I have a 4 memory slots. Does it mean that it chooses just one of the memory slots?

NUMA is only applicable to multiprocessor systems, i.e. those with more than one physical CPU. The NUMA nodes are essentially couples of CPU + memory:

On such systems, allocating the entire RAM disk to a single node improves the performance (interconnect and remote access are more "expensive" in terms of resources).

Most consumer-grade PCs are single-processor, so the selection of NUMA node is not available there.

Andrew,

Thanks for the great answer. So, since I don't multiple CPUs, I should just leave the NUMA node option unchecked, right?

In your case, there will be only one NUMA #0, so checking or unchecking this option will have no effect.
