I did notice a few interesting things:
running both wu-ftpd and dkftpbench on the same system
and trying to do 400 users at 1000 bytes/sec each
gets you realtime signal queue overflow within a few minutes.
This doesn't happen when wu-ftpd is running on a different
machine. It's an interesting drawback to the realtime
signal notification scheme: if the machine isn't dedicated
to the server using it, it doesn't work well.

Also, when benchmarking an ftp server, it pays to use
tcpdump to monitor udp and ident traffic to make sure
your ftp server isn't slowing itself down with them
if you don't want it to. (The default ftp server
shipped with redhat does.)
