Hi, sorry to bump up on an old post. But this shows up when I search for clustering in PM2.

I'm still new in nodejs. My question is, does it really needed in all production use case?

Yes I'm aware that it improves the speed a lot, but in my use case, I use chokidar to watch a directory, and then fork a child\_process for uploading it to S3 every time new file added.

When I tried to run PM2 in cluster mode, and it does the same thing twice. How can I improve the app performance without getting this?

It's a little late 😅 but,

Extract chokidar in a separate process so that you don't have to run it in the cluster.
