Using Varnish and the redis vmod without a backend

we are using the exact same setup for an API (redis backend responses
delivered by vcl_error) sending out about 15000 responses per second
over a single virtual machine.
Indeed single clints with a high RTT have a limited performance, but for
us this does not matter.

Sincerely,

Tobias
