Which is Faster / Memory Efficent

[Sayian]

I just upgraded to PHP5 , and id have to say ive seen a slowdown in my script execution time ...

Is php 5 not faster then 4? Should i have upgraded?

I dont use OO programming , so was their really a need?

Anyone else had experiances like this?

Perhaps an example of code being used. I am yet to see any speed difference from PHP 4 to PHP 5. However using OO and functions PHP 5 is marginally (not enough to make a difference) faster than PHP 4 from a few tests I did back when seeing if I should upgrade.
