performance questions && php project size

[Nameless12]

I am using a lot of recursion in terms of array iterators and directory iterators

I am also using a LOT of objects, I am not using them all the time but they are there. Its a long story as to why I have so many but each time  I make a div object i get a style and attribute object created inside them. So each time I create a table all the elements of the table have style\attribute including the table it does start to add up.

My code is spread over 133 files and is 230k I have one image that is 30k so 230 -30 = 200k of script. I am probably nearing 7000 lines of code and I have not even started to design the site and I got a little slowness every now and then. I think its slow the first time as its adding the project into cache the first load.

I would like to hear how big projects are getting to give me some idea of scale because by the time i build the site ontop of this it will probably put the size at around 20,000+ lines.

Also if anyone has performance tips in terms of what I can get away with, what i cant get away with and server configuration I would like to hear it. And if you dont mind tell me the size of your projects to give me something to scale against.
