Overview

Node pool contains two worker-threads pool implementations , you don' t have to deal with worker-threads complexity.
-The first implementation is a static thread pool , with a defined number of threads that are started at creation time .
-The second implementation is a dynamic thread pool with a number of threads started at creation time and other threads created when the load will increase ( with an upper limit ), the new created threads will be stopped after a threshold.
+The first implementation is a static thread pool , with a defined number of threads that are started at creation time and will be reused.
+The second implementation is a dynamic thread pool with a number of threads started at creation time ( these threads will be always active and reused) and other threads created when the load will increase ( with an upper limit ), the new created threads will be stopped after a configurable period of inactivity.
You have to implement your worker extending the ThreadWorker class

Installation

``` -npm install node-pool --save +npm install node-thread-pool --save ```

Choose your pool

+Performance is one of the main target of these thread pool implementation, we want to have a strong focus on this.
+We already have a bench folder where you can find some comparisons. +To choose your pool consider that with a FixedThreadPool or a DynamicThreadPool ( in this case is important the min parameter passed to the constructor) your application memory footprint will increase .
+Increasing the memory footprint your application will be ready to accept more CPU bound tasks, but during idle time your application will consume more memory.
+One good choose from my point of view is to profile your application using Fixed/Dynamic thread pool , and to see your application metrics when you increase/decrease the num of threads.
+For example you could keep the memory footprint low choosing a DynamicThreadPool with 5 threads, and allow to create new threads until 50/100 when requests, this is the advantage to use the DynamicThreadPool.
+But in general , always profile your application +
