Hi I need help about chr routerOS I'm using because now v6.49 is there no issue there? Because I did a bandwidthtest for 10g port, he only got it from TCP both (send and received) he only got 5-6G but when UDP is okay, the bw test, how can I maximize the 10G port? Any suggestion, this is the specs of my CHR "Intel (R) Xeon (R) Gold 5222 8cpu, 2gb RAM "hosted from Esxi v7.

What bandwidth test did you use? Bandwidth Test built into mikrotik devices relies heavily on the CPU and never seems to give true results.

Iperf or Iperf3 between devices on each side of your CHR will give a better indication of performance "through" your router.
