This is **not** correct. Every line of application code added to the
dispatch cycle will only reduce performance, so when you are
attempting to improve the speed of your application, these results
show exactly how much room for improvement you have.
Let me just make everything clear. What Paul is getting at is that
you
can't get any better response times than the hello world
application. If
you're hitting those numbers you just can't go any faster. There is
nothing more you can do about it but to customize the framework code.
Not entirely what he's getting at. What he's saying is that without
caching, this is the baseline. You can definitely add caching to speed
up the processing, and only if you still need additional performance
should you start customizing the framework code.
Matthew, that's pretty close, but not quite the whole thing.
You can cache processing results (either data or views), but if that
caching happens at the action-method level (which I think is the most-
likely case), then you are not likely to see any increases past the
results I've posted. This is because the dispatch cycle has to pass
through the bootstrap, front controller, page controller, and action-
method to begin with; the only part that remains is the action-method
code and the view rendering.
In my testing, there is no action-method code, and you can't get
faster than "do nothing" there. Similarly, the view rendering is only
to present a static text "hello world" and I don't expect a caching
system will be able to outperform that. So the results I show are the
fastest a dynamic dispatch can occur.
Full-page caching will *definitely* speed things up, but that is only
because the framework is being sidestepped entirely; the web server is
sending a static (cached) page from disk at that point.
Hope that helps to illuminate the testing results more clearly.
