This might be a better place to post this. We’re running into a bottleneck issue and haven’t been able to root it out yet. We have a B24 link that can only do about 220 Mbps total TCP throughput with a PHY of 1170/1170, MAC of 702/702. SNRs of 25-25-30-30.They’re all plugged into a Netonix WS-12-250-DC.
The Netonix is showing zero errors on the ports, and I’m not getting any dropped packets when I bandwidth test from Mikrotik hEX behind a CPE to a hEX plugged into the Netonix. Flow control is set to “Both”. When using 2x40 Mhz channels vs. 2x80 Mhz channels, the UDP throughput doubles as expected, but the TCP throughput is the same at ~200-220Mbps.
Any thoughts that could be causing this? Some interaction with the switch?
Moderator note: Just a FYI, this is the same post as TCP bottleneck from Netonix to A5c to C5c’s so people don’t get confused.
