Hi Ron,
TIMING AND PERFORMANCE: -T[0-5]: Set timing template (higher is faster) --min_hostgroup/max_hostgroup <msec>: Parallel host scan group sizes --min_parallelism/max_parallelism <msec>: Probe parallelization --min_rtt_timeout/max_rtt_timeout/initial_rtt_timeout <msec>: Specifies probe round trip time. --host_timeout <msec>: Give up on target after this long --scan_delay/--max_scan_delay <msec>: Adjust delay between probes
By tweaking those options, you can probably squeeze some extra performance out of it. Of course, you have to be careful; if you set it to scan too fast, you might miss hosts and ports. It might take some experimentation to get it set up properly.
Thanks this great tips, I searching in nmap manual for this, but a conclusion test is more slow (remember 3.000 hosts), i've a fear per timeout and problems with old 2-Mb wireless latency.
