A simple thread-safe, header-only performance timer for CPP (c++). A dedicated thread will collect data and print all timers periodically.
// Case 1: the simple case
perf_timer::Timer timer_simple("simple");
// do something that we concern
usleep(100);
timer_simple.end();// Case 2: the cumulative case
perf_timer::Timer timer_cumulative("cumulative");
for (int i = 0; i < 1000; i++) {
// do something
usleep(10);
{
// something that we concern
timer_cumulative.CumStart();
usleep(i * 10);
timer_cumulative.CumEnd();
}
// do something
usleep(10);
}
timer_cumulative.CumReport();// Case 3: record a perf counter
for (int i = 0; i < 10; i++) {
perf_timer::PerfCounter::Record("throughput", i * 100);
}
