Package p384 is an AMD64-optimized P-384 implementation.
The majority of elliptic curve operations done during certificate chain validation are on P-384, but P-384 implementations are unoptimized (unlike P-256). I observed code that does a lot of chain validations easily spending more than two-thirds of its time in P-384 ScalarMult, so I wrote this.
// Standard library implementation.

// Our implementation.

BenchmarkScalarBaseMult-4 10000 179281 ns/op
