Performance hit when enabling HTTP/2 on VPS

so you want to enable HTTP/2 and wonder if you can make modifications on the profile to make the performance hit lower?

every form of processing will add load, there might be some figure what a HTTP/2 profile will do, but that is probably something your F5 local contacts can provide.

good chance the answer will be it is impossible to predict reliably.

if you have a test environment and some performance testing equipment you might be able to test something. or again ask your f5 contact if they can work that out?
