Code snippet to make benchmarking code performance easier.

[DelinWorks]

inline const char* benchmark_bb7_name;
inline std::chrono::steady_clock::time_point benchmark_bb7_start;
inline std::chrono::steady_clock::time_point benchmark_bb7_end;
#define BENCHMARK_SECTION_BEGIN(name) benchmark_bb7_name = name; benchmark_bb7_start = std::chrono::high_resolution_clock::now();
#define BENCHMARK_SECTION_END() benchmark_bb7_end = std::chrono::high_resolution_clock::now(); \
fmt::print("benchmark {} took: {} millis, {} micros", benchmark_bb7_name, std::chrono::duration_cast<std::chrono::milliseconds>(benchmark_bb7_end - benchmark_bb7_start).count(), std::chrono::duration_cast<std::chrono::microseconds>(benchmark_bb7_end - benchmark_bb7_start).count());

this pollutes namespaces but can be improved @aismann

Usage:

BENCHMARK_SECTION_BEGIN("name_of_benchmark");
    // code that takes CPU time
BENCHMARK_SECTION_END();

Thanks for sharing.

if you have a function that you want to check it's time then you wouldn't find any real differences, that's why you need to run that function too many times between begin and end, like 40,000 times, and with that value you can base your benchmarks on it when changing or improving code

Im using AXLOG so no extra include is needed

inline const char* benchmark_bb7_name;
inline std::chrono::steady_clock::time_point benchmark_bb7_start;
inline std::chrono::steady_clock::time_point benchmark_bb7_end;
#define BENCHMARK_SECTION_BEGIN(name) benchmark_bb7_name = name; benchmark_bb7_start = std::chrono::high_resolution_clock::now();
#define BENCHMARK_SECTION_END() benchmark_bb7_end = std::chrono::high_resolution_clock::now(); \
AXLOG("benchmark {%s} took: {%i} millis, {%i} micros", benchmark_bb7_name,                                    \
       std::chrono::duration_cast<std::chrono::milliseconds>(benchmark_bb7_end - benchmark_bb7_start).count(), \
       std::chrono::duration_cast<std::chrono::microseconds>(benchmark_bb7_end - benchmark_bb7_start).count());

you can remove the curly brackets if you want, they're pointless

I know. But I likes.
BTW: It's helping me to improve the class DrawNode too
