4x sounds excessive, but in fact TS code is a significant performance penalty for windows, the only place where thread safety is "supported". I'd challenge you to do a non-TS build on windows and set up an fcgid pool of php workers and compare -that- to linux. I'd expect very nearly identical performance, once you factor out kernel-specific differences in the link-loader/resolver. Those are likely two very different beasts. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
