"limit_rate" (http://nginx.org/r/limit_rate) can control the
kbps-response-writing speed of a single request, using whatever criteria
you like, using things that are available at response-writing time.

"limit_req" (http://nginx.org/r/limit_req) and limit_req_zone can control
the rate of incoming requests that are processed, using whatever criteria
you like, using things that are available at request-reading time.

I'm not aware of a way to trivially combine the two.

Cheers,
