I will note that these numbers reflect the fact that some header
fields are intentionally set as ephemeral so that they are never
stored in state. If I run the test again without that flag set for any
of the fields the numbers come out as...

REQUEST:
               size  time | ratio min   max   std
     http1  200,876  0.00 | 1.00  1.00  1.00  0.00
       dhe   40,957  0.06 | 0.20  0.00  0.71  0.14
    delta2   35,850  0.34 | 0.18  0.03  0.67  0.12
headerdiff   38,673  0.29 | 0.19  0.03  0.88  0.16

RESPONSE:
               size  time | ratio min   max   std
     http1  160,435  0.02 | 1.00  1.00  1.00  0.00
       dhe   35,350  0.02 | 0.22  0.00  0.67  0.12
    delta2   42,764  0.66 | 0.27  0.02  0.65  0.10
headerdiff   46,321  0.57 | 0.29  0.04  0.84  0.13

I still have more testing to do, of course, but that's where things stand now.
