PHP 4.0 is extremely fast as it is, and is running at equivalent speed to
mod_perl (your mileage may vary, but many people say it's faster, and I'm
sure there are people for whom it's slower). However, it doesn't do
post-compilation caching (and as a matter of fact, neither does mod_perl,
other than a very specific and not all too usable mechanism of read-only,
static shared compiled scripts).
There's no doubt that you can deploy your web site without purchasing the
Zend Cache, and on the other hand, there's no doubt that deploying it with
the Zend Cache will result in much better performance (the Zend Cache is
actually a bit of a misleading name, because it does all sorts of things
other than just post-compilation caching). In most cases (almost all cases
I've seen to date) - using the Zend Cache is the most cost effective
alternative, compared to alternative solutions (i.e. hardware). It's
really a question of what kind of performance you require, and whether PHP
4.0 as it comes out of the box is quick enough for you.
