JSON Benchmark

Benchmark JSON library performance in C/C++.

Requirement

  • A modern compiler or IDE supporting C11 and C++17.
  • CMake 3.5+ for building this project.
  • Git for interacting with the submodule in this repository.

Building

Clone this repository and initialize submodules:

git clone https://github.com/ibireme/yyjson_benchmark.git
cd yyjson_benchmark
git submodule update --init

Build and run:

mkdir build
cd build
cmake ..
cmake --build . --config Release
./run_benchmark -o report.html

If you want to build with other compiler or IDE, try these commands:

# Clang for Linux/Unix:
cmake .. -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++

# Microsoft Visual Studio for Windows:
cmake .. -G "Visual Studio 16 2019" -A x64
cmake .. -G "Visual Studio 16 2019" -A Win32

# Xcode for macOS:
cmake .. -G Xcode

# Xcode for iOS:
cmake .. -G Xcode -DCMAKE_SYSTEM_NAME=iOS

If you want to build for arm64 device, you should add flag-DSIMDJSON_IMPLEMENTATION=arm64 for simdjson.
