Benchmark scans

nmap-* are with Nmap trunk. nmap-perf-r* are revisions from the nmap-perf branch.

Guide to notation

0:02:08
10–34–355		means that a scan took 0:02:08, had 10 hosts up, 34 open ports, and 355 closed ports.

The first round of testing was done with the options as shown above. perf-random-hosts is 9991 random IP addresses. perf-down-hosts is 500 (initially) down addresses. perf-up-hosts is 656 (initially) up addresses. perf-lan-hosts contains 192.168.0.1 and 192.168.0.190, two live hosts on my LAN.

No scan delay

The second round of testing was with Nmap trunk and --max-scan-delay 0. I was trying to see if scan delay could be isolated as the cause of scan time variability.

The scans are mostly the same as in the first round, except for the maximum scan delay and the host lists. This time I used a list of 30 /26 netblocks (1920 IP addresses total).

Remove dynamic addresses, no scan delay

The results from round two still vary too much. I went through the list of hosts and culled any blocks that seemed to be dynamic address ranges. That left 11 /26 netblocks (704 addresses total). I then re-ran the tests with this list in the file perf-random-hosts-2. perf-up-hosts-2 and perf-down-hosts-2 are groups of 200 up and down hosts from the list of 704.

What's the right speed to scan anyway?

Because the overall times taken are still fairly variable, I was curious about what really is the optimum fixed rate at which to scan these hosts. I made a script rate-test.sh that ran multiple scans at fixed rates near the hosts' supposed rate limits. These graphs show the results of several trials using nmap-perf r11480.

On the left is a UDP scan of a Linux host with a nominative rate limit of 1 ICMP reply per second. It seems the optimal scanning rate is actually 1.1 send per second, but going even a little faster than that incurs a penalty. It may be because there are 5 open|filtered ports that we can go a little faster than we think. Every scan in these tests was 100% accurate (5 open|filtered, 95 closed).

On the right is a TCP scan of 30,000 ports on Mac OS X, with a supposed RST rate limit of 250 per second. The rate limiter had been settling in at around 150 packets per second. You can see that around 230 sends per second scan times become quite variable. Worse, much about 150 sends per second the scan is not always 100% accurate. There should be 3 open ports and 29997 closed, but some ports were found filtered at 160, 170, 190, 195, 200, 205, 215, 220, 225, 230, 235, 240, 250, 255, 260, 265, 270, 275, 280, 285, 290, 295, and 300 sends per second.

I repeated the experiment with nmap trunk (with fewer trials, using some revision near r11480) just to make sure it was the same as nmap-perf (it should be when using a fixed rate).

The results are the same. So with this in mind I'll leave no more than 5% headroom between the maximum sending rate and the measured receive rate.

Green is nmap-perf, blue is nmap, and orange is old nmap.

nmap-perf wins up-F, random-F, and down-ping. The one slow time for nmap-perf/up-F is because of a wrong rate limit set to 1.00 on one host. It took almost 300 s longer to scan than the others.

nmap-r11204/random-F is amazingly consistent, considering that test includes a ping scan and a port scan. nmap-r11204 was the fastest in the scanme test.
