Here are my results on FireFox 3 beta2 with firebug 1.1b10:
Console in debug:
Notice the two errors in the console.
Loadtimes in devel:
Loadtimes in production:
Notice the big problem seems to be base2-dom-fp.js which takes over half a
second to load. How many of these files are required?
I'm not sure why it took 88ms to load a 4k static CSS file either. Or 65ms
for the 80byte file.
These numbers represent with everything cached they varied between 1.1 and
1.4 seconds for the page load.
Maybe I'm being too picky and 1.4 second load times are acceptable fully
cached and local? My second Grok app has no CSS or JS and loads in 18ms.
Then I tried to reload after clearing my browser's cache with ctr-shift-del
and i get 13 second load times!
This was easily reproducible. kukit.js is the culprit every time and takes
12 seconds to get passed to the browser. Also obviously nothing is rendered
while this occurs and it did not matter if KSS was in devel or production.
