Often a single thread (which corresponds to a single network queue) is not sufficient to achieve maximum bandwidth. You should experiment with increasing the number of threads used by your application if possible.
Consider using tools like Task Manager or PowerShell to pin application threads to the NUMA node or CPU cores local to the network device. For some workloads, such as storage I/O, moving the application to a non-local node provides benefit.
