Advice on concurrency value

[Rory-Powell]

Is there any advice on what to set the concurrency to when using queue.process()? i.e.

• What is the recommended value to set in relation to the system resources available?
• What are the downsides to setting this value to a high number? say 50-100

The best is actually to make some tests to find out a sweet spot. Normally jobs that are just IO intensive can be parallelized a lot in NodeJS, so having a high concurrency like 300 is not unusual, but if the jobs are more CPU intensive you would probably lower this value a lot and maybe even use sandboxed processors where the jobs will run in separate OS processes.

Thanks for the feedback @manast !
