  *  You can also use [http://www.pylot.org Pylot] to test the application's behavior under load, and get more reliable results (+ in a nicer report form).

+I tested the "Welcome" application and found that it executes up to 86
+request/second on my local environment. A similar value has been reported to
+the web2py group, and it seems to be the maximum we can expect (considering
+that the "Welcome" application is really thin).
+
+UltraCore requires response times for interactive views strictly below 250ms
+on an average computer, so that we can execute up to 4 requests/second. That
+sounds perhaps very slow, but compared with what we currently have, this
+would be a 4x speed-up.
+
+So, if you implement a new view, please check whether it loads that fast on
+your local computer (use FireBug to test), and if not - look at first at the
+model, then at the static contents (ExtJS? Load only necessary components,
+not ext_all.js!), and then at the controller (you will find that the
+controller is mostly the fastest component of all).
