I'm going to go out on a limb here... it would probably make your
application faster if you used a file based cache for content to be
eval'd and then included the cached file instead. Then whatever
accelerator is in play can do it's thing on the code.
But the poster didn't ask about content in general, he asked about the
difference between include and eval'ing content acquired from a file.
Cheers,
