EscientPronto takes 3.5 seconds to start up as it is 300K+ of source code. You are correct that it is likely compilation time.

this code will save you some time and cut down on size of script.
note that this[varname] declares a field in the object where script(function) is located (Page or Activity).

function d(varname,tag,v)
{
var w = GUI.widget(tag);
if (w) w.visible=(v!==0);
this[varname]=w;
}
d("but11", "but11", 1);
d("b11o1","11o1",0);
etc...

Note that you could also define a panel that contained string with multiple lines

butt11|butt11|1
b11o1|11o1|0

Then, immediately following compilation, write a function to split() the string as needed and then loop through the values calling function d() above. This way, you minimize compilation time but may still incur overhead parsing the string the first time through.
