Well, several possible issues.. It probably isn't the best of all ideas to have BOTH IP firewalling solutions installed and running at once. This will add some overhead. Pick one and stick with it. And why do you have DUMMYNET running? There is a new version of IPFilter in -CURRENT if I recall correctly, and this may be related to your timing issues. Really you ought to just take IPFILTER out of your configuration. Aside from that, you'll need to use 'top' or some similar utility to find out where and why you're CPU-bound for FTP transfers. Find out if you're primarily stuck in the kernel, or if some userland utility is sucking it up (like natd, but your ipfw rules tend to rule out accidentally running ethernet traffic through natd).
