I'm trying to reduce the number of probes sent per port for
TCP and UDP scans.

I've searched the source code and strace'd Nmap. I thought
perhaps someone else here had done it already?

Nmap-3.50 sends approx 16 TCP SYNs for a filtered port.
My aim is to reduce the time taken to do a full port scan
and by sending less probes per port be slightly more
stealthy. Ideally I'd like one probe per port sent, I know
this may affect the reliability of the results.

What command line options are you using?
