Goal is to compare timing on similar set of functions(named and anonymous) for:

Load time: JS load and compile, no execution.
What is the impact of smaller footprint for named functions?
Execution time of
- Var as reference to anonymous function:
  var FunctionScr3Var27=function(){ window.RealCount=27; }
  Funtion - local named function:
  var function FunctionScr3Var27(){ window.RealCount=27; }
- Each - full set, all functions are called
- Half set: initialize all, but run each even function to see the promise of smaller load time for uninitialized variables.
  Set var SkipEachOdd=true; before JS include. In JS itself:
  if( !SkipEachOdd || 1 )FunctionScr3Var27();
- Global - functions are declared in window scope.
- Local - functions are declared in function scope:
  function GblFunctionScr3Var(){
  ...
  var FunctionScr3Var27=function(){ window.RealCount=0; } if( !SkipEachOdd || 0 )FunctionScr3Var0();
  ...
  }GblFunctionScr3Var();

Additional requirements:

Display file size for each test
Show backend render time
each generated function name shall be unique to avoid hash name optimization: another test shows that overriding is faster than new declaration.
Run test on various browsers, collect results on public blog
