[deluge-web] Cache static ressources

Postby lildadou » Thu Mar 08, 2012 1:26 pm

Hello,
I find that the web page of deluge-web is very long to load.
The main reason is that the JavaScript files are downloaded each page opening. As I use nginx in front, I added a rule that queries on static files (ico, css, js, gif, jpg, png) was treated with an additional header who caching response on the client side (Cache-Control).

  • Context : min/max (size)
  • With forced cache rule : 1,97s/2,11s (3,89KB transferred)
  • Without forced cache rule : 13,69s/13,72s (850,99KB transferred)
  • First load (no client-side caching) : 14,72s/15,20s (859,72KB transferred)

My version is 1.3.4-dev (from git repo). Does the cache is used in the final versions?

Awesome idea. How difficuly is it to set up nginx as a front-end? I've only touched it a few times.

Thanks for the configuration, I'll try taking a look at it. I suppose the proxy could be used by programs like Transdroid as well who just access the JSON-RPC.

Another good optimization would be to smack together all the small icons into a single stripe. It's become pretty common on the web lately, and it does save quite a few requests in this case. I don't really know how to use them together with ExtJS, but surely it is possible.

HTTP pipelining may be sufficient?
