Matt,
This couldn't happen with any other js-engine, because of the ECMAScript
semantics. The code that creates request handler closure is executed only
once, which means that the closure is created only once.
Cheers,
Fedor.

I don't know where you heard that, but it's not true of V8 (or I doubt of
any modern JS engine). There are plenty of benchmarks out there that can
prove this.
You can however separate out for basic code hygiene - you get a lot of
indentation with nested callbacks.

It is created only once.
However, if you define function in a closure - it'll be allocated each time
the closure is executed.

In the plain javaScript world I've learned that nested functions can be
problematic because the inner function is "re-created" every time the outer
function is called. Apparently the inner function is garbage collected and
the constant re-creation of it has a cost on performance.

Not sure what "code for clustering in a post request handler
First of all, it's a bad idea to extend native prototypes. Some third party modules can rely on that, etc, etc. So instead of `child.kill` you could write external function and call it as `kill(child)`. Ohh... that sentence looks weird... poor children. There is also a possibility to capture requ
Hi Tushar,
being a little more specific about what you are trying to accomplish and
sharing some code would help.
Have you tried one of the many clustering examples google has found?

Usually you wouldnt need to write any clustering sp
