Re: TCP performance

I think is not a MikroTik problem. With these bandwidths, latency plays against. I think one main problem of NV2 is the jitter of the latency. TCP frames arrive asynchronly to the NV2 TDMA time slot, sometimes they get through within 1ms mostly within 3ms, but sometimes with 15ms (one out of 100). ...

On heavy load hours, ping is about 15ms, and total traffic about 20mbps.
