I'm starting a project to improve Nmap's performance and the
predictability of the length of its scans. This may involve tuning
performance parameters, adjusting the congestion control mechanism, or
other things not thought of yet.
What complaints do you have about Nmap's performance? One thing I have
heard is that for very large scans Nmap may be too slow, or the time
taken may be too unpredictable.
One possible improvement is I've identified is that sometimes scan delay
kicks in when I don't think it should. If a scan has just started and I
see the scan delay go from 0 to 5 ms I'm likely to kill the scan and
start it over.
Write back with possibilities you see for improvement. I'd like any
changes we make to be in response to actual user concerns.
