include/require vs performance

i am designing a small app that obviuosly works best when I have a lot of global files with functions, which cut down on editing. I will likely have a main page that will contain modules and also load all of the required includes like config etc. in total some 10 files will be reqested. Is there, was there ever issue around including a lot files via include(). I am running things on a local server so it's hard to gauge. Thansk in advance.
