Upstream connection between nginx to varnish - HTTP2

[Andrei]

How do you guys deal with large request rates when offloading SSL? For
example, Hitch/Nginx do 5k requests/second, which then get sent to Varnish
and that's another 5k requests/second. This causes a tremendous spike in
internal connections which ultimately increases resource consumption
two-fold, and reduces the maximum number of requests per second which can
be handled via HTTPS. This is honestly one of the main reasons I'm
considering moving over to Nginx which can handle both, to cut down on the
tremendous amount of internal connections/requests, especially considering
UNIX sockets cannot be used yet. Over HTTP we can easily serve 10k+ reqs/s,
however 10k+ reqs/s over HTTPS causes some massive issues, even on a tuned
32 core server with 128GB RAM + NVMe disks
