I guess daisy chaining and splitting on the A1200 clockport is out of the question then.
Please don't think I was blaming Poseidon for the slow speed of the Subway/USB ethernet solution, I'm aware it's the clockport that is the real bottleneck.
But surely a new, dedicated clockport ethernet card would work with less RAM than using a USB ethernet card through Poseidon. I wouldn't have expected significant speed increase, but at least a card like this would be of use to people with un-accelerated Amigas with clockports and extra RAM, especially since PCMCIA ethernet cards will reduce most 8MB cards to 4MB, and 4MB isn't fun to use online.
