I read from the celery documentation that we can autoscale concurrency by using autoscale option while starting a worker.

I have added 200 task in my queue and each task takes 5seconds to finish. I started worker with autoscale of 3 min concurrency and 15 max concurrency , but its starting with only 3 processes and I am not seeing any scale up in the number of processes.

Using celery with rabbitmq.
