PHP4 vs PHP5 Beta 3 : memory usage

Hi all, I wanted to compare the memory usage of PHP4 and PHP5 (Beta 3) on a same script. And i observed a strange problem. So, here is a small test (if you want to reproduce it). First, i write a small and short php script. It just make a simple memory_get_usage() (with a number_format for the presentation :p) : <?php print number_format(memory_get_usage(), 0, ',', ' ').' bytes'; ?> Second, i write a small shell script to call 100 times my php script by HTTP. I used lynx. And i stored the result in a logfile. Here is the code : #!/bin/sh for (( i = 1; i <= 100; i++ )); do lynx -dump http://localhost/armel/mem.php >> php.log done And here is the result... ---------------------------------------------------- With PHP4.3.4 (axps module) : armel@omble:~$ cat php.log 27 232 bytes 27 232 bytes ... ... 27 232 bytes 27 232 bytes ---------------------------------------------------- With PHP5 Beta3 (apxs module too) : armel@ombre:~$ cat php.log 211 952 bytes 153 784 bytes 108 184 bytes 157 680 bytes 94 376 bytes 107 392 bytes 446 888 bytes 558 712 bytes ... ... 107 392 bytes 446 888 bytes 557 656 bytes 211 952 bytes 153 784 bytes 108 184 bytes 157 680 bytes ---------------------------------------------------- The result under PHP4 is logical. But under PHP5 Beta 3, i think it's very very strange. What do you think about this ? Any idea ? Maybe my script can even be a good system of random pulling :)) Regards (and happy new year), Armel.
