Hi, I thought I'd mention that Caolan did some experiments [1] with the parser from node.js. The idea was to get all the parsing done fast in C. I don't know the it's current status, and it looks like it's written for CHICKEN 4 only.
[1]: https://github.com/caolan/snowy In my opinion, spiffy is quite fast. Can I ask why you want to use microhttpd? K.
