You're probably more likely to get useful tips if you can show your
starting point, and describe what result you want.
is a few years old, but does include a link to the specific tests that
were done then.

It also has a link to a sizing guide with some numbers when using nginx
as a reverse proxy.

Maybe what you see as "a drastic drop", is normal, if every http request
involves a new from-scratch tls connection?

Good luck with it,
