Alt BN 128 Benchmark

About

We need to know, how much BPF instructions will be used for every operation on elliptic curves. We can't to know it directly, but we can compare the time needed for these operations and time, needed for Keccak hash for the same data. These benchmarks allow us to approximately define the amount of data in bytes for ellicptic curves operations and Keccak hash and compare result times.

Example of Usage

Starting 1000 rounds of ALL benchmarks on the random data of 256 bytes:

alt-bn128-bench --count 1000 --size 256

Same as above, but in short notaion:

alt-bn128-bench -c 1000 -s 256

Start only specific benchmark with default values:

# Start Addition benchmark
alt-bn128-bench add

# Start Multiplication benchmark
alt-bn128-bench mul

# Start Pairing benchmark
alt-bn128-bench pair

Starting 1000 rounds of Addition benchmark on the random data of 256 bytes:

alt-bn128-bench --count 1000 --size 256 add
