Woah it's working great for me today! Apparently because my changes to
enable edge-caching finally kicked in overnight (I used Brandon Wirtz's
excellent instructions
here<https://groups.google.com/forum/#!topic/google-appengine/6xAV2Q5x8AU/discussion>).
So now I have only one dyno instance and it doesn't seem to ever create a
second one even though setting is auto/auto.
Which makes sense: now a new user page load results in 2 request (html and
ajax call) vs 40 (including static resources). I still see the static
requests in logs, but with a 204 instead of 304, and taking consistently
about 23ms instead of up to couple hundred depending on file size. So they
probably return so quickly the queue never grows much if at all.
Interestingly, the Requests count in the instances page only increases by 2
(so not reporting the served 204s).
Last thing: My static cache settings filter sets a random expiry between 5
and 6 minutes, so even though every couple minutes a resource will actually
have to be served, it's one at a time:
resp.setHeader("Cache-Control", "public, max-age=3" +
Math.round(Math.random()*9) + "0");
resp.setHeader("Pragma", "Public");
Hope this helps!
