the way create_function works (internally)?

Actually I think I´ve missed (misunderstood) what create_function() is for... For any reason I thought functions created with create_function() should be created faster. I´ve stressed my server with some performance tests and the result was that the create_function() created function performed worse than declaring a function manually... If someone could provide an example what create_function() is for (not how to use it, I already know) and what´s the advance then declaring a function directly (typing it).... -- o----------0-¬---------O-·---¬----o---®-----o o O ° . | http://www.kiffen.de | pRoteçt y0ur bRaín |0 O ° ¤ ° · 0°·³°²'²³-¹'³´³°^°³~³²³°'³²²¨³²^³¹³²°²³`³º³°Þ ° o © ° . · | psychedelic experience | gott@kiffen.de | O ° o ° o-¬--o--0-----©-·--O-----o-----0-¤----------o 0 ° · ° . ¤ ·
