Hi, What happens if you remove the -R for both TCP and UDP? Is it the same situation? Note that in this case the receive throughput is what is measured on the server side.
Also, I suggest to try TCP with different packets lengths, using the -l option. Default is 128KB, so trying 1k, 8k, 32k may help understanding the issue.
