Can anyone *really* explain opcode caching with PHP?

I'm interested in your reasons for this. My experience with mod_php is
that I get huge performance improvements with opcode caching (my app
loads a lot of code and libraries). If you don't use opcode caching, is
there a better way to get the same benefits?
