`--script whois-ip' will take too long time for runing.

[Hongyi Zhao <hongyi.zhao () gmail com>]

Hi all,

See the following for detail:

--------
werner@debian:~$ nmap 178.63.103.81 -n -Pn -T5  --script whois-ip --
script-args whodb=nocache

Starting Nmap 6.47SVN ( http://nmap.org ) at 2015-03-15 20:05 CST
Nmap scan report for 178.63.103.81
Host is up (0.47s latency).

As you can see, the above command is so slow -- completed after 678.32 
seconds.

But the performing on the whois command is quickly in my case:

---------
$ time whois 178.63.103.81 |tail -3
% This query was served by the RIPE Database Query Service version 1.78 
(DB-3)

real    0m4.623s
user    0m0.000s
sys     0m0.004s
--------

Any hints on this issue?

Regards
