Randall Dow kindly pointed me in the direction of a really awesome project called picolisp. (Is it already everything Arc should be?) It's a really concise Lisp dialect with a built-in database. Somehow it is really performant without a compiler, taking the code as data idea so seriously that the (quote ..) operator is used in place of lambda. It also refuses to use strings or arrays as a datatype and includes a flight sim!
This is the kind of no-nonsense, excellent, innovative software that it's a real pleasure to use.
What gives me less pleasure is the discovery that it is faster than tpd2 for serving dynamic webpages.
Using this simple script which Alexander Burger very quickly cooked up,
#!bin/picolisp lib.l (load "ext.l" "lib/http.l" "lib/xhtml.l") (de foo () (html 0 "Hello" NIL NIL (ht:Prin "hello " (get 'name 'http)) ) ) (let (P (port 8080) H "@foo") (setq *Home (cons H (chop H))) (loop (when (listen P) (http @) (close @) ) ) )
picolisp achieves around 4.3k requests/second on my humble laptop. As tpd2 only gets 3.8k, it looks like I need to crank out the optimization juice and get back to the drawing board. Congratulations picolisp!
(Unfortunately, picolisp is cheating somewhat, as it can only serve one request at a time in this mode, so one slow client might block all the others. In normal mode it uses a fork mechanism that limits it to 0.7k or so. However the project is so awesome I'm going to overlook this.)
A number of other rather lame contenders have claimed to challenge the tpd2 performance crown but haven't made good on their boasts. I tried a few, but now I'm going to say stop: unless you yourself can at least beat PHP/Lighttpd or something comparable (which is slower than tpd2 according to my tests, at about 3.2k on my laptop), sorry I'm too busy.
UPDATE 20090809 — teepeedee2 is now much faster than PicoLisp.
