Can anyone *really* explain opcode caching with PHP?

Additionally, one has to take into account that opcode-caching and the
like that zend, apc etc. do only usually gives you a couple of percents
of increased performance.

When you get "slashdotted", that is basically useless.

What you have to do is aggressive output-caching via varnish or nginx
(we haven't done this, yet, but I assume it's possible since some time,
too).

That will give you much (x-times) more performance than an opcode-cache
will ever be able to.
