Dragan, Thanks for the report. We have an old report of this on our tracker at http://issues.nmap.org/1026, where the user reported the slowness began in Ncat 6.45, and using Ncat 6.40 as the sender avoided the issue. Apart from that, we have http://issues.nmap.org/1025, which is for optimizing the socket read and write buffer sizes; fast networks ought to be able to handle larger buffers, but we use a fixed size.

Dear All, I try to use ncat in combination with ffmpeg. I am piping output to ncat. Troughput is extremley low and I am getting less than 1fps which is 250kbit/s on recievers end either trough loopback or abother host. On the other hand with nc64 it rocks but I am missing multiple connections feature. I followed instructions and installed npcap and registry acceleration keys on windows 7. Could you please let me know am I making a mistake somewhere , or maybe you are able to replicate the problem and potentially fix it. Kind Regards.
