Re: Extremley low throughput of ncat

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.
