I do not understand why but I have experienced this a number of times.

1. 2 SXT's point to point - configured bridge and station bridge using nv2 routerOS 5.24
2. bandwidth test shows - 100mbps +
3. real-time internet bandwidth shows increased latency at 6 mbps+
4. Why?
5. Noise floor -117 dbm, tx/rx connectivity - 63/67 dbm

As always, what is your configuration?

i believe you test it via the udp...
you should test it by using tcp then u will get the same result.

and, test both direction instead of one direction.
btw, can you print screen on the status???
