Node - Why Is Node More Performent

Why Is Node More Preforment?

1. No overhead of creating processes, assigning threads, and switching context between threads, this is since execution uses a single thread which is dedicated to executing javascript in its entirety.
2. Javascripts native support of first-class function and the use of call-back functions and closures, enables fast & correct access to results of long running operations.
3. Node actually enables using all the CPU cores (if lets say your using quad core), and this is done quite simply with node js.
