with full HTTP/2 HPACK encoding patched Nginx, the subsequent runs of h2load will show increasing 'space savings' in headers section up to 90-99% i.e.

Code (Text):

headers (space savings 90.00%)

as opposed to Nginx's default partial HTTP/2 HPACK implementation which would see header space savings capped around 18-22%

 

nope both aren't enabled by default

 

Space savings depends on actual content and its header response sizes for your page you're testing
