They do not cache HTML results.
They cache the compiled binary of your script, and keep it in RAM, so that
the next page hit is simply a GOTO (JUMP) instruction, rather than having to
load your PHP script from disk (SLOW), parse it (slow), compile it (slow)
and *THEN* finally actually execute it.
Zend Cache gives a minimum 200% performance boost.
Others more like 20-50% performance boost.
The Optimizer will usually give a significant boost only with inexperienced
coders who are doing silly things. :-;
