Not really, but this depends on your workload.
Every reload gracefully shutdowns old workers. This means that if
there are long-lived requests (big downloads from clients with
slow links etc.) old workers may still be here for a while. And
they still consume memory and so on. In my practice shutdown time
reached several hours in some cases.
If you reload every 15 seconds and shutdown takes longer - you
have problem.

Thanks for the quick reply.
But what is the right way for dynamic weight management of upstreams?
