[Users] onload time

[Robert Buckley]

hi,

my app takes (according to firebug) 


...39.87s (onload: 26.93s)


This is rather long for an app which isn´t really big.


Do the following make a difference to the loading time?

 - Minifying the js?

 - removing the parts of ext.js that are not used ..ie custom build

 - removing the parts of openlayers.js that are not used..ie custom build

 - using postgis instead of shapefiles

 - removing all js from the html doc




are there any others?...which has the best result regarding performance and 
useability?


Cheers for any thoughts,


Rob
