It's not noticeably slower, whether you use require or include depends on your needs, not which one is faster. Any speed difference might matter if you have 10 million include statements on your page, otherwise don't worry about things like that. There are much larger bottlenecks in programming than nanosecond differences between things like that. A single database connection will provide far more overhead than anything like require vs. include.

JSG has already given you the answer but apart from that if you want to track on execution time of php scripts you can install xdebug and enable to 'cachegrind' http://www.google.co....47883778,d.bmk which will profile your script. you can use wincache application or webgrind (web based cachegrind viewer) http://www.google.co....47883778,d.bmk to view the profiling in user friendly GUI
