  for (var i=0; i<length; i++) {
	  longString += Math.random() < 0.1 ? ' ' : String.fromCharCode(65+Math.floor(Math.random() * 30));
  }

var totallyDifferentLongString = createRandomString(600000);
var endDiffLongString = longString + ' different';
var startDiffLongString = 'different ' + longString;
var sameLongString = '' + longString;

var shortString = createRandomString(100);
var totallyDifferentShortString = createRandomString(100);

var RUNS = 10000;

Tests:

Long Equality
for (var i=0; i<RUNS; i++) longString === sameLongString
Start Long Difference
for (var i=0; i<RUNS; i++) longString === startDiffLongString
End Long Difference
for (var i=0; i<RUNS; i++) longString === endDiffLongString
Totally Long Difference
for (var i=0; i<RUNS; i++) longString === totallyDifferentLongString
Totally Short Difference
for (var i=0; i<RUNS; i++) shortString === totallyDifferentShortString
