Dave Collins 2994f0ff44 secp256k1: Optimize NAF conversion. ... This significantly optimizes the NAF conversion code by rewriting it to avoid all heap allocations as well as switch to an O(1) algorithm. The following benchmark shows a before and after comparison of the NAF conversion as well as how that translates to scalar multiplication and signature verification: name old time/op new time/op delta ---------------------------------------------------------------------- NAF 1.16µs ± 1% 0.08µs ± 1% -93.02% (p=0.008 n=5+5) ScalarMult 138µs ± 1% 135µs ± 0% -1.77% (p=0.016 n=5+4) SigVerify 164µs ± 0% 162µs ± 0% -0.98% (p=0.008 n=5+5) name old alloc/op new alloc/op delta ---------------------------------------------------------------------- NAF 96.0B ± 0% 0.0B -100.00% (p=0.008 n=5+5) ScalarMult 816B ± 0% 720B ± 0% -11.76% (p=0.008 n=5+5) SigVerify 1.54kB ± 0% 1.44kB ± 0% -6.25% (p=0.008 n=5+5) name old allocs/op new allocs/op delta ---------------------------------------------------------------------- NAF 2.00 ± 0% 0.00 -100.00% (p=0.008 n=5+5) ScalarMult 15.0 ± 0% 11.0 ± 0% -26.67% (p=0.008 n=5+5) SigVerify 32.0 ± 0% 28.0 ± 0% -12.50% (p=0.008 n=5+5)		2021-08-12 05:00:01 -05:00
