A method for binding input/output (I/O) objects to nodes. The method includes binding an I/O object group to a NUMA node of a plurality of NUMA nodes on a system, obtaining an I/O object group size of the I/O object group, and determining an I/O object group target size based on an I/O object group aggregate load of the I/O object group. The method further includes comparing, by the NUMA I/O Framework, the I/O object group target size and the I/O object group aggregate load, determining, by the NUMA I/O Framework, that a difference between the I/O object group target size and the I/O object group aggregate load exceeds a threshold, and instructing, by the NUMA I/O Framework, an I/O Subsystem associated with the I/O object group to change the I/O object group size, wherein the I/O Subsystem changes, in response to the instruction, the I/O object group size.
