Hi Marcus,

did we change from non ZTS to ZTS builds on MacOS? ZTS builds do a bunch
of additional copying of tables.

Nope. Thread Safety is disabled.

I did my comparision with PHP 5.2.5 and PHP 5.3-Snapshot.
Both versions were compiled with a simple ./configure without any
additional parameter. bench.php was executed with the CLI SAPI.

Here are the tables for PHP 5.2.5

simple 0.328
simplecall 0.405
simpleucall 0.660
simpleudcall 0.767
mandel 0.993
mandel2 1.253
ackermann(7) 0.993
ary(50000) 0.050
ary2(50000) 0.048

Hi

This commit is responsible for the bad performance:
http://cvs.php.net/viewvc.cgi/php-src/configure.in?r1=1.579.2.52.2.77.2.11&r2=1.579.2.52.2.77.2.12&diff_format=u

-gstabs versus -g should have no effect on production performance.

Ok, maybe i made a mistake, that's what i compared:
