No, 2.2 and 2.4 don't default to prefork, it's suboptimal, most linux distros have moved away from it... > Recently we had a bug with the new Apache 2.4 API where apxs doesn't answer > about the MPM configuration anymore, leading to a ZTS build by default. > This bug has now been fixed, was > https://bugs.php.net/bug.php?id=61172. Wrong fix. Out of the box you don't know which mpm may be loaded, because the mpm is now loadable (although a full daemon stop/start is necessary). The only mod_php loadable under any circumstance is TS enabled. If you want php/linux single-child, fastcgi is the only rational approach. > I dont know anything about windows, sorry Always threaded.
