greatroar 255ba83c4b Parallel index benchmarks + benchmark optimizations ... createRandomIndex was using the global RNG, which locks on every call It was also using twice as many random numbers as necessary and doing a float division in every iteration of the inner loop. BenchmarkDecodeIndex was using too short an input, especially for a parallel version. (It may now be using one that is a bit large.)
