Rustler Benchmarks

A collection of benchmark to test the performance of certain rustler features.

Running a benchmark

Each module can be run as a benchmark on the command line. Note that the benchmark crate is compiled with mode release!

$ mix run -e Benchmark.NifStruct.run
Name                        ips        average  deviation         median         99th %
decode                 404.50 K        2.47 μs   ±651.07%        1.63 μs        7.23 μs
decode and encode      117.27 K        8.53 μs   ±306.83%        6.34 μs       33.76 μs

Comparison:

decode and encode      117.27 K - 3.45x slower +6.06 μs

$ mix run -e Benchmark.NifRecord.run
Name                        ips        average  deviation         median         99th %
