include() files

[demetri007]

i am curious how include('afile') statements affect the performace of the webapp. are there any benchmarks i can check out?

It doesn't. If you're including a file which has no php in it you should use readfile because then it's not parsed but that's an optimisation using readfile rather than an overhead with include. If you're looking to optimise your code then I suggest looking at I/O operations such as DB and Disk access.
