What is the difference between Swing and AWT?
...
Because Swing tries to do everything possible in Java other than the very raw graphics routines provided by a native GUI window, it used to incur quite a performance penalty compared to AWT.

My benchmarking loops:
function arrpush_small() {
var arr1 = [];
