Hi all,

I'm using PHP 5.1.6 & 5.2.1.
Is there any known performance issue with PHP 5.2.1?
With the same script, same php.ini, same extensions, same apache (of course), I'm getting a huge difference.

For example, with a microtime difference between start & end I get:

- PHP 5.1.6: 111ms avg.
- PHP 5.2.1: 205ms avg.

Also, If I compare the results from the xdebug profiling extension it gets worse (322ms vs. 22ms). I can send the zipfile (69k) containing the two cachegrind files if needed. The code is a little complicated because it uses our framework with an autoprepended file and using __autoload, but you'll see that the function calls are exactly the same.

Thanks in advance.

I brought this issue up before using Linux, but it was all in my
imagination apparently :)
