tracker issue : CF-4181256

Problem Description:

ArrayEach in CF11 is vastly different in performance to ArrayEach in CF10.

Steps to Reproduce:

<cfscript>
// test the performance of iterating through an array
// Array converted to ArrayList to pass by reference
// Regular array in CF
// using standard for loop
// Compare CF 10 vs CF11 and CF2016
// CF10 is much faster than the others


// setup our test data
foo = [];

for( i = 1; i<10000; i++){
    foo[i] = i;
}


// test 1 : Using ArrayList and ArrayEach
startTimer();

asList = CreateObject( "java", "java.util.ArrayList").init( foo ); 

ArrayEach( asList, function( e ){
   var shoe = asList[e];
});

stopTimer();

startTimer();

ArrayEach( foo, function( e ){
    var shoe = foo[e];
});

stopTimer();

startTimer();

size = ArrayLen( foo );

for( i=1; i<=size; i++){
    shoe = foo[foo[i]];
}

stopTimer();

function startTimer(){
    variables.start = getTickCount();
}

function stopTimer(){
    WriteOutput( getTickCount()-variables.start & "<br>");
}
</cfscript>

Actual Result:

Slowness on CF11

Expected Result:

Same performance as CF10

Any Workarounds:

Convert your array to ArrayList first.
