fast: through middleware inserted at 0
slwr: through middleware inserted via @use@
rotr: through endpoint sent via the router
bare: through ActionController::Metal with self.response_body
cntr: through ActionController::Base with self.response_body
text: through ActionController::Base with render :text
tmpl: through ActionController::Base with simple render :template
layt: through ActionController::Base with render :template with layout
Note: These tests are being run without ActiveRecord, which currently
has an extremely slow connection pool implementation. It might
be impossible to improve this implementation, but straight
framework benchmarks should compare reasonably with frameworks
without ORM support

After first round:
* Memoize commonly used request methods
* Use faster run_callbacks method
* Eliminate the need to check superclass for callbacks changes each time
* Improve log subscriber by remembering list of loggers
* Small improvement to performance of MessageVerifier
* Use simple Request methods in Logger middleware because the more advanced
versions aren't available yet but are slower anyway
* Stop the flash middleware from pulling in the session even if it's never used

Third round:
* Improve LookupContext, more to come
* Avoid constantly going through the whole PathSet coercion logic
* Add AS::Dependencies.ref, which returns an object you can call #get on to get
the real object

Exceptional work. 550 rps more for Sinatra apps plugged into the router, and 175 rps more for simple actions like AJAX methods that return text :-) Great stuff! Look forward to seeing more :-)
