You might try other operating systems. I don't know how well FreeBSD
compares, but I have had good luck on both Solaris (x86) and Linux 2.4.

Depends on what you want to model. Do you want keepalive enabled? Do you
want to simulate 7000 simultaneous connections, 7000 requests, or 7000
"users" (depending on your definition of a "user")?

We'll happily accept patches if you have any. :)

You could implement your own hooks in flood that simple disable output 
(or count
and don't display the results until the end).

Getting megaconglomerate working will probably have to wait until
someone who needs it implements it.
