TimerLuaIntf

Timer calls between C++ and Lua with LuaIntf.

Just a test.

Conclusion

• Lua is fast.
• LuaIntf is good.
• Call from Lua to C++ is faster than from C++ to Lua.

Build

1. Install conan.
2. conan remote add remote_bintray_jinq0123 https://api.bintray.com/conan/jinq0123/test
3. conan install --build missing

   PROJECT: Generator visual_studio created conanbuildinfo.props
   PROJECT: Generated conaninfo.txt
   

4. Use sln to build. Select Release config.

Output

C++ calls lua add() many times:

C++ calls lua add_times() once:
 0.436400s wall, 0.436803s user + 0.000000s system = 0.436803s CPU (100.1%)
Lua calls C++ add() many times:

Lua calls C++ add_times() once:
 0.000005s wall, 0.000000s user + 0.000000s system = 0.000000s CPU (n/a%)
