piscina VS poolifier

Workers multi-threading via Tinypool (a lightweight fork of Piscina)

For threading best to use piscina and for clustering best to use pm2 which does not even need one line of code change in Node.js code.

We used piscina at it was quite good: https://github.com/piscinajs/piscina

We used Benchmark.js for benchmarking and piscina as a pool for worker threads. benchmark.js was used to run the same code in 2 scenarios - one using a single thread and one using the piscina pool. The degree of parallelism was passed to the program via an environment variable. The test code is present in worker.js in both the cases.

piscina for managing node's worker threads

One other thing...this passed by in my feeds last week, I’m not an expert in web workers or browser threads etc, but it seems like it might be relevant, so sharing it just in case:

“A fast, efficient Node.js Worker Thread Pool implementation”

This is by no means a complete list of what piscina can do.... checkout the official docs here.

At work I use https://github.com/pioardi/poolifier

We have an api used for generating reports from mongo dB to csv, this let's the report process in the background leaving the report api to still handle requests.

Since that I am familiar with Java programming language, I immediately started to look for thread pool implementations just like are present in java. There was only one small and not exhaustive thread pool at that time, so I started to implement poolifier. I choosed to implement two thread pools, a fixed-size thread pool and a dynamic-size thread pool so that users could tune and choose which one fits better for their applications.
