lib/rand: Optimizations ( #7964 )
...
rand.secureSource.Uint64 no longer allocates. rand.String uses a
strings.Builder. Benchmark results on linux/amd64:
name old time/op new time/op delta
SecureSource-8 69.1ns ± 3% 51.7ns ± 3% -25.21% (p=0.000 n=20+10)
String-8 2.66µs ± 2% 1.95µs ± 1% -26.61% (p=0.000 n=10+10)
name old alloc/op new alloc/op delta
SecureSource-8 8.00B ± 0% 0.00B -100.00% (p=0.000 n=20+10)

lib/rand: Break out random functions into separate package
...
The intention for this package is to provide a combination of the
security of crypto/rand and the convenience of math/rand. It should be
the first choice of random data unless ultimate performance is required
and the usage is provably irrelevant from a security standpoint.
