kune load time
Loading kune.cc in my browser (Firefox 16.0.2 running in ubuntu 11.04) takes a lot of time (20 sec). I analyzed kune.cc load time with http://loads.in and I have identified the heaviest file: http://kune.cc/ws/8979F3EE0E91487C5ED8DEFE0ACDD438.cache.html that takes around 15 sec. to load. (it is more than 700 KB).
This will only happen the first time a user goes to kune.cc if the user have the browser cache activated, and it will happen every time if the user's cache is not active(for instance if user has the "do not remember history" option in the browser's configuration).
I believe 20 seconds is more than enough to be worried about kune's load time.
