php<->CL/QSH very slow

[jogisarge]

Hello,

i try to call a php-script on our 520.

CHGVAR     VAR(&CMM) +                                   
             VALUE('/usr/local/Zend/Core/bin/php +       
             /www/zendcore/htdocs/test.php')
QSH        CMD(&CMD)

i try to send an email in the php script and i was wondering why it takes about 5-8 seconds to send the mail.
So i tried to find out where the script is slow.
For testing i have made en empty php-script.
if i test this the script runs 3-4 seconds.

-> the time must be lost in the communication between CL/QSH and PHP.

Is there another faster way to call the php scripts ?
Are there params that can speed up the communication ?

Thanks so far
