How can I speed up a 1800-line PHP include? It's slowing my pageload down to 10sec/view
- by somerandomguy
I designed my code to put all important functions in a single PHP file that's now 1800 lines long.
I call it in other PHP files--AJAX processors, for example--with a simple "require_once("codeBank.php")".
I'm discovering that it takes about 10 seconds to load up all those functions, even though I have nothing more than a few global arrays and a bunch of other functions involved. The main AJAX processor code, for example, is taking 8 seconds just to do a simple syntax verification (whose operational function is stored in codeBank.php).
When I comment out the require_once, my AJAX response time speeds up from 10sec to 40ms, so it's pretty clear that PHP's trying to do something with those 1800 lines of functions. That's even with APC installed, which is surprising.
What should I do to get my code speed back to the sub-100ms level? Am I failing to get the cache's benefit somehow? Do I need to cut that single function bank file into different pieces? Are there other subtle things that I could be doing to screw up my response time?
Or barring all that, what are some tools to dig further into which PHP operations are hitting speed bumps?
