Some incomplete data: I work mostly on Drupal, and in the next version we're 
splitting up the code base into a lot more smaller files that we can load 
conditionally.  The benchmarks we've done so far indicate that without an 
opcode cache there's a huge benefit in speed from not loading/parsing code 
that we're not going to be using (there's a lot of it at this point) as well 
as a sizable reduction in RAM usage.  With an opcode cache the speed 
difference is negligible, but I believe there's still a RAM savings 
per-process.  More on that when we've completed the process.

So it all depends on your caching configuration and use-case.  Loading a ton 
of code that you never use is not good for performance.

"If nature has made any one thing less susceptible than all others of 
exclusive property, it is the action of the thinking power called an idea, 
which an individual may exclusively possess as long as he keeps it to 
himself; but the moment it is divulged, it forces itself into the possession 
of every one, and the receiver cannot dispossess himself of it."  -- Thomas
