Your numbers suggest you can do 5 requests per second per worker, ie 300 per minute per worker, so it seems that you have ample resources. However you'll probably need to do some testing to confirm this as it would only be true if CPU is your bottleneck (as opposed to database concurrency for example) > Is it also useful/necessary to use this ? > allow_concurrency: true > > not sure what that is without some context.
