Compile Apache2 in Multithreaded Mode?

yottabit

I couldn't find a USE flag for compiling Apache2 with multithreading mode (as opposed to the traditional multiprocess mode like Apache1).

Has anyone thought about adding this option? Should I submit a bug report / feature request?

I guess I'll poke around with the local ebuild to enable it in my server...

Cheers,

J

look at the eclass file, it's easy to change there, but beware of modules that taint the apache non threaded, because they aren't thread-safe.

ah yes, I went into the ebuild file, turned on multithreads...

Recompiled... apache2 yells about my php not being thread-safe and to recompile php.

So I recompiled php. Started apache2.

Load my gallery page... the time went back UP. Incredible.

Apache1 took average 15s. Apache2-prefork took average 12s (20% speed improvement!). Apache2-worker took 15s.

So what is the point?

I suspect the gallery PHP code is primarily monolithic and cannot take advantage of the multithreading abilities.

So alas, for now, back to Apache2-prefork.
