Google has long since ingrained into my brain how important every millisecond is when dealing with large amounts of traffic.

In this post, I'm going to demonstrate a really simplistic way to improve your PHP website performance.  It seems to go against the grain of "old school" vanilla PHP writing, but the results are incredible!  By removing the use of require and include and replacing it with a spl_autoload_register function instead, the time savings are more than 10 times!

Not only that, in theory it's less lines of code!
