Hi Alvaro,
Here is the output I get for: AC_SYS_LARGEFILE
checking for special C compiler options needed for large files... no
checking for _FILE_OFFSET_BITS value needed for large files... no
checking for _LARGE_FILES value needed for large files... no
I added the following in macro.h(line 219) to go around the issue:
#ifndef _FILE_OFFSET_BITS
# define _FILE_OFFSET_BITS 64
#endif
Also, finally I stressed a little bit cherokee on Tiger to try to see
if it was stable by running:
$ab -c 10 -t 30 -k http://localhost:8181/

The good news is that the numbers are pretty sweet even if just
synthetic. (btw this is on a 7450 PPC G4 @ 1.67Ghz)
I got the following output from the console where cherokee was launched:

I had never seen the "no such file or directory" before though.
Marko, did you see this one as well?wwww
Now, another good test was to compile will poll support instead of
kqueue, and the results are actually much better! Same test on the
same machine returns:

Wow! it went from ~3000 to 5000 req/sec I would have thought kqueue
would be better performing than poll. Maybe the error message we are
getting above is hurting performance... Or it is maybe an incoherent
behavior in OS 10.4 that even though not clearly acknowledge by
Apple, has been witnessed by several other open source projects using
kqueue. Oh well, we'll see, it looks like OS 10.4.3 is right around
the corner.
Anyway, Alo, I think that if we disable kqueue on OS X for now,
cherokee is looking quite stable and showing good performance. I
attached below a crude result from apache on OS X on the same
machine, same page requested (prefork).
Actually this may be jumping to a different topic, I think it would
be nice if you defined some standard benchmarking tests to run on
cherokee so that after each new release those exact same test could
be run on various platforms and against the other mainstream servers
(apache, lighttpd, etc..) to make sure that cherokee's main feature
(performance and scalibility) is maintained throughout new releases.
Later,
Sébastien
