PHP execute very slow : PHP Version 5.2.6

Hi, I'm experiencing very slow performance of my php scripts ... At first and for a long time I thought it was Oracle fault cause I didn't use binding (I rewrote the code ), but the performance is still bad. So I tested my sql statement and did some time measurement and found out that Oracle can fetch 300 records in less then 2 seconds, but PHP needs 210seconds ... to display it to the user .... I'm using default php.ini I have a horizontal menu with buttons to switch pages ..... and just switching pages takes time with minimum or no oracle interactions. My php version: 5.2.6 OS: Windows XP sP3 and Windows Server 2008 Testing it in PHPEd using internal PHPEd server and FastCGI ... and also on Windows 2008 server in IIS ...same results .... both using the same php.ini.... Would anyone know what could be the cause of this ? Any hit is appreciated. Kris
