Just now I was working on integrating and optimizing networking for some microcontroller-based software (using lwIP). At the end, I&#x27;ve reached 7MB&#x2F;s send and 10MB&#x2F;s bulk receive speed.<p>I just did the calculation. It says for 10MB&#x2F;s I&#x27;d need 80MHz. The chip runs at 84MHz. So, it&#x27;s pretty close :)
