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. 


Thanks
