No, that option is unchecked. I did disable the nessus TCP portscanner. 
Nessus does not do any portscanning, I've verified this.

I have looked at another tcpdump trace. It's not every plugin, but it 
happens fairly often. I see no delay, and delays of 2 to 6 seconds. 
Let's see. There are about 2400 HTTP plugins, so a 4 second delay on all 
of them causes a 2h40 delay. Possibly less if both threads are doing 
HTTPS checks in parallel, possibly more when there is more than 1 HTTPS 
port on the server. This explains a lot. I can't figure out what is 
causing these delays though.

It looks like it is the HTTP attacks, yes. But that could just be 
because there are so many of them (20% of the plugins are HTTP plugins).
