Have you found out anything new about this? I noticed the same, TLS over TCP gives me 1gbit, everything else around 300mbitThere is a few different threads on AX3 performance.
Interestingly if you run iperf3 test with udp you will get full speed
For me,
iperf3 over tcp: 160mbps down 280 up
iperf3 over udp: 1005mbps down 1010 up
fast.com 1010 (tls over tcp)
smb file copy: 160mbps down 280 up
scp file copy: 160mbps down 280 up
Definitely something odd going on especially since tls seems immune to the issues presented by regular tcp connections, My only advice is to consider opening a support case, as that's the only way things like this can get fixed.
Edit: Adding an observation I just had this morning.
In tests above, I had AX3 connected by eth1 to mikrotik sfp+ @2.5gb link to a CSR317. Moving to eth2 @ 1gb had same results, however moving off the CSR317 to a CSR328 no longer using SFP+, I get 300mbps bi directional on iperf3 tcp run, still not as fast as udp or fast.com but interesting how that made an improvement.
