Re: database contest article
Hi Tomas, I just tried to roughly benchmark the forking server and I do not think it is a limiting factor. With the following code That's right. For a database benchmark it is not a limiting factor, this will be more on the db side. However, if I try a non-forking server #!bin/picolisp lib.l (load ext.l lib/http.l lib/xhtml.l) (allowed () @start) (de start () (html 0 Hello NIL NIL Hello World! ) ) (let (P (port 8080) H @start) (setq *Home (cons H (chop H))) (loop (when (listen P) (http @) (close @) ) ) ) I get roughly three times as many transactions, compared to the forking server. I also did $ siege -b -c 5 http://localhost:8080 But, as we saw already, this is only for an empty server. For real applications the difference will be neglectible, especially as the fork occurs only once for each session. Cheers, - Alex -- UNSUBSCRIBE: mailto:[EMAIL PROTECTED]

PicoLisp is not trying to be clever in the above way. You think Apache is faster than the PicoServer despite all its I don't know. I did not make an opinion on this yet. bloatedness, maybe through the fact that it's compiled? PicoLisp and its web server is mostly compiled too. But we could argue about that one for ever;-) That's one of the reasons I found the discussion about Lisp in hardware interesting (link posted at the beginning of this thread).

Re: database contest article
Hi Tomas,
Have you tried to rerun your solution and what improvement
(trans/min) did you achieve?
Unfortunately not ... Actually, my compagnon Josef Bartl wrote it
initially. He urged that we participate. I did some tuning then, and he
did the testing. After that, both of us were busy, so we did not try
again. It is also a bit tedious, the system has to be set up, and
certain functions in lib/http.l need to be redefined to suit that
client simulator.
I must confess that in the beginning I did not want to participate in
that c't contest, as was never interested in optimizing PicoLisp for
speed, and always favored simplicity over fancy optimizations.
Actually, the error was minuscule. We submitted picoLisp-2.2.1.pre,
which still had - in src/io.c - the code
for (x = data(c1); isCell(x); x = cdr(x))
if (!isNeg(caar(x)) (n=(int)unDig(caar(x))/2)!=fd
FD_ISSET(n,fdSet)) {
Push(at,val(At)), val(At) = caar(x);
prog(cdar(x));
val(At) = Pop(at);
break;
}
Unfortunately, it was not before picoLisp-2.2.3 that it was fixed. By
simply removing the 'break'! :-(
Cheers,
- Alex
