Crypto speed

Crypto speeds, part of NetworkSpeed

Poly1305 Verify (https://download.libsodium.org/doc/advanced/poly1305.html)

  • When benchmarking code uses lambda and class-template, instead direct hard-wired function, it seems to perhaps slow down by up to 3%
  • For sizes smaller then ~1500 it is quite important to have size N*64. Especially avoid N×64+1.
  • 1472 (ipv4) is a "round" (N×64) size
  • Best speed could be: 5.48 Gbps on AMD for @8960 messages (fitting into 9000m MTU).
  • On Intel best speed seems to reach 14.5 @1472 and 18.5 Gbps @8960 Test WDeb9_20171103_040600
