These benchmarks were run on an Intel(R) Core(TM) i7-6560U CPU @ 2.20GHz processor, on Linux 5.12.5/Fedora 34, and run against commit 54adf3b. The Rust compiler version was rustc 1.55.0-nightly (b41936b92 2021-07-20). The exact code and data used to run the benchmark can be seen here.
Uniform
A benchmark on randomly-generated numbers uniformly distributed over the entire range.
Simple
A benchmark on randomly-generated, simple numbers to test parsing numbers with few digits, Each number is in the range [0, 1000] (or [0, 50] for u8).
Large
A benchmark on randomly-generated, large numbers to test parsing numbers with many digits.
Simple Negative
A benchmark on randomly-generated, simple, positive and negative numbers to test parsing numbers with few digits. Each number is in the range [-1000, 1000] (or [-50, 50] for u8).
Large Negative
A benchmark on randomly-generated, large, negative numbers to test parsing negative numbers with many digits.
Simple
A benchmark on pre-computed, simple values generated via NumPy. The data was generated as follows:
np.random.randint(0, 100, size=10000, dtype=np.uint8)
np.random.randint(0, 500, size=10000, dtype=np.uint16)
np.random.randint(0, 500, size=10000, dtype=np.uint32)
np.random.randint(0, 500, size=10000, dtype=np.uint64)
[random.randrange(0, 500) for _ in range(10000)]
Random
A benchmark on pre-computed, uniformly random values generated via NumPy. The data was generated as follows:
