Improved "fieldSorter"
function fieldSorterOptimized(fields) {
var dir = [], i, l = fields.length;
fields = fields.map(function(o, i) {
if (o[0] === "-") {
dir[i] = -1;
o = o.substring(1);
} else {
dir[i] = 1;
}
return o;

When I was 18... 18 years old, I saw for the first time in my life... I saw an image of clarity. I saw a comic strip... a three panel comic strip that, though simple as it seemed, changed me... changed my being, changed who I am... Made me who I am...
Enlightened me...
The strip, Garfield, the comic strip was new... no more than maybe a month and a half since inception, since... since coming into existence... and there it was before me in print, I saw it... a comic strip... What was it called?
Garfield.

Thread Pools

Thread pools on the JVM should usually be divided into the following three categories:

  1. CPU-bound
  2. Blocking IO
  3. Non-blocking IO polling

Each of these categories has a different optimal configuration and usage pattern.
