I'm checking how to optimize my cron execution in the reindex action, and I saw the option to run the index job in a separated process.
How does it work? can it be helpful to optimize the execution?
If you are having issues with the indexes cron execution and your server is CPU optimized, yes you can use a separate process for it.
