As a PHP developer I can tell you exactly where one huge bottleneck is: POST-Redirect-GET. The current paradigm for handling POST requests requires that I initialize my framework, load all my objects, create a new object, save it in the database then set fire to the whole thing and tell the browser to redirect to another page where I initialize my framework, load all the objects, recreate the object I just burned down and plug it into the relevant view.
Not being able to respond to a POST request with a view with a "if the user wants to bookmark this page or reload it, please GET this Location: instead" doubles the number of requests I have to serve and halves my throughput.
