To answer my own question:Since we're on roughly on the topic, does anyone have experience with UDP speeds of the RP2040 + W5500 combination? A quick 5-minute test using the Arduino libraries gave only a few Mbps. I have yet to try it with Wiznet's library and the Pico SDK. For it to be useful to me I'd like to see closer to 10 Mbps, which I understand might be stretching it considering the SPI overhead.
This is with the Pico SDK. Perhaps a tiny bit of optimization is still possible, but this is roughly what you get. The ratio of UDP payload throughput to SPI speed is better than expected actually.
