And that's what happens now if you do any amount of use of classes. Unless you buy the Zend Optimizer, anything that uses classes requires tons of recompilation of the PHP code for each page. We found that we were spending 20% of real response time just recompiling the class files for each page.
This performance tweak is just a drop in the bucket compared to that.
