It uses a static cache (default size 65k entries). One entry takes
56 bytes, if I don't mistake.

I haven't tried 50++ Mbit/s of worms, but it works on 100Mbit/s of live
traffic, which is full of worms. The answer is: it depends on how
large is your CPU and how quick are your worms. Try it and tell me
how it goes. :)
