teepeedee2

And libev is a C wrapper around epoll and other system calls. There's not much code needed to use epoll directly, that's what John Fremlin's TPD2 web server (the previous "world's fastest Common Lisp web server") did: https://github.com/vii/teepeedee2/blob/master/src/io/epoll.l... What libev provides is a very portable wrapper around all the different non-blocking IO system calls in all the different Unixes. That's the hard part.

Wish I could up this one more. I am in the process of playing with Lisp (in my case, Common Lisp, the SBCL variant to be specific) and I would love to see people with production services in any Lisp, or even Scheme. I have been very attracted to the idea of Lisp, specifically as I discovered teepeedee and teepeedee2 as being some of the first truly fast web servers [0], and now I found wookie,[1] an evented web server running on top of libevent. I really want to play with that. The closest thing I know of to people running "prod services on Lisp" are the Untyped guys in the Racket Scheme community [2], and not much else. I know pg and company became famous on Viaweb and Lisp, but since then there are scarce examples. However, the amount of bitching libraries and cool books (pg's book included) make me want to buck the trend and do it

How about tpd2? If you're comfortable rewriting everything from scratch, at least you'll be working from a high performance foundation -- http://github.com/vii/teepeedee2/tree/master Weblocks is a very good concept if you're willing to get your head round it, and work within its worldview (which is about displaying widgets rather than manually generating HTML). Everybody uses parenscript, which is a great concept.
