How to achieve 10Gbit/s on small UDP packets?

Hey /r/networking

I have a unique problem that requires fast throughput of 9k packets through UDP, currently with my current benchmarking i can only achieve 3-4Gbit/sec, i have increased the buffers to their max limits on windows and also increased MTU on my network cards to 9k. Is this an issue where the payload is too small to take advantage of the bandwidth?
