RE: eEye Digital Security ports nmap to Windows NT

See Q175523.  (for those Windows-illiterate folks, this is a KB article 
available at support.microsoft.com.)  This is most likely the problem.  Try 
rebenchmarking w/ this registry value set to 0.

yeah, we've seen some serious slowdown in the tcp scanning, and i am looking
at a way to speed this up.  the big problem in this scan is the overhead
with establishing a full tcp session, followed by windows tcp RST packets.
i've syn scanned hosts on the local network in less than a second, and all
the syn code uses direct calls to the ndis driver, competely subverting the
winsock layer, giving it a serious speed advantage.  However, we are working
on a service release that should fix some problems that have come in.  i'm
not certain on a timeline for this release, due to other work related
concerns, but it is coming, along with (probably) a gui frontend, win  9x
port, and a nmapnt specific mailing list.

hope this helps

I don't have a working Windows box at the moment, but when I do I will
certainly check it out and probably merge the port into the mainstream
tree so it doesn't fall behind.  Also, it is critical that I run some
benchmarks.  If the NT version is as fast or faster than UNIX, I have
some
very important optimizing to do :).

It doesn't appear to be an issue...
