When I run the benchmark test on my MacBook I observe that for 1MB payload GRPC is almost twice as fast as UDS. It was mentioned that "To get better performance in large sizes, I had to add some kernel buffer space over the defaults, which lead to close to double performance". Anyone know how to add "some kernel buffer space over the defaults"?

Results below:
