This example was described in more detail in a blog post: https://krzmaz.github.io/2022-08-15-creating-a-web-server-on-raspberry-pi-pico-w-using-pico-sdk-and-lwip/
In my testing it reached ~20x performance of the MicroPython implementation from point 3.9.1 of https://datasheets.raspberrypi.com/picow/connecting-to-the-internet-with-pico-w.pdf
If you want to test this example with your html files, just add/edit them in the src/fs directory and rebuild the project!
NOTE
This project was only tested on Linux and MacOS, I haven't prepared it for Windows.
If you need that, feel free to contribute a PR or reach out in the issue section!
cp cmake/credentials.cmake.example cmake/credentials.cmake
# <fill in your credentials>./build.shThe built USB Flashing Format file will be located in build/src/pico_w_webserver.uf2 - just copy it over to the Pico W to flash it!
Now the example uses Server Side Includes (SSI) to introduce dynamic data into the HTML responses.
As per documentation:
SSI-enabled pages must have one of the predefined SSI-enabled file extensions
Which means that no cost should be introduced in non SSI pages
