  1. Hi if i have to run heavy cron jobs on a server and every minute i can run heavy memory consuming processes inside that cron as concurrent processes, what do you suggest would opening a new worker thread solve my issue since i believe i am running in Javascript out of heap memory violation when running 10 heavy processes under promise.all while when i run a single process it seems to work fine.

  2. Hi all,

    Any have an idea about the execution of the worker thread. Does this worker thread utilize all System Core or run on single thread?

    1. Martin,
      That would still leave you limited to the amount of work the main thread can do. Everything will just run slower. I would not recommend this approach.
      With worker threads, the program gets access to a new CPU core where new work can be done.
