Hi there!

NUMA is the Non-Uniform Memory Access Architecture. The basic feature of the NUMA server is that there are multiple CPU modules, each CPU module consisting of multiple CPUs (for example, four), and has independent local memory and I/O slot ports.

Because the nodes can communicate with each other through the interconnection module, the access speed of each CPU to the local memory is faster than that of the shared memory and the local memory of other CPUs. Therefore, the upper layer senses NUMA, allocates resources within a node, and improves performance significantly on a service server that is closely related to a specific task or user.
