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) :
[EMAIL PROTECTED]:~$ cat php.log
27 232 bytes
27 232 bytes
...
...
27 232 bytes
27 232 bytes
----------------------------------------------------
With PHP5 Beta3 (apxs module too) :
[EMAIL PROTECTED]:~$ 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.
