System and method for boosting up performance of NVMe-TCP transport

A computer program product residing on a non-transitory computer readable storage medium having a plurality of instructions stored thereon which, when executed across one or more processors, causes at least a portion of the one or more processors to perform operations comprising:

• using free central processing unit (CPU) cycles for processing Non-Volatile Memory express Over Fiber (NVMeoF)/Transmission Control Protocol (TCP) sockets;
• wherein using the free CPU cycles for processing the NVMeoF/TCP sockets includes exposing a character device with a callback that iterates over the NVMeoF/TCP sockets for processing, wherein the callback includes an Input Output Control (IOCTL) callback;
• and
• adding the NVMeoF/TCP sockets to a waiting list, wherein each of the NVMeoF/TCP sockets holds an atomic state and each of the NVMeoF/TCP sockets is configured to be processed by a storage management application thread or a kernel thread (kthread), and wherein a software interrupt adds the NVMeoF/TCP sockets to the waiting list to process the NVMeoF/TCP sockets upon the IOCTL callback being called by the storage management application thread.
