Benchmark

If you want to do benchmarks of some iroha components, put them in this folder.

We use google benchmark.

To enable build of benchmarks, specify an option -DBENCHMARKING=ON during configure step:

$ cmake -DBENCHMARKING=ON ..

Note: changing CMAKE_BUILD_TYPE from Debug to Release can significantly speedup execution, thus heavily changing benchmark results.

To build iroha and benchmarks in release mode, type:

$ cmake  -DBENCHMARKING=ON -DCMAKE_BUILD_TYPE=Release ..

Note: all code inside benchmark function influences on the benchmark results.

How to write benchmark

1. Include #include <benchmark/benchmark.h>.

2. Refer to official google guilde.

Also, try to preserve namespacing by making directories inside benchmark directory.
