Update performance documentation. #78

Open ShaneHarvey opened 7 years ago

ShaneHarvey commented 7 years ago

The "performance" section in the documentation has not been updated since April 2014. Running the benchmarks today with go 1.7 and 1.8, it seems this library is slower than the stdlib in all but one benchmark (BenchmarkSHA256Large_*):

Go 1.8:

Unless you run on ARM: On ARM 32-bit, spacemonkey is 10x faster than stdlib for my server.
