@17336 上面的issue是contention profiler。cpu profiler 不完整可以确认下是不是栈帧回溯有问题，issue里提供的信息比较少不太好直接定位问题，可以尝试的办法比如编译加-g和-fno-omit-frame-pointer，确认编译过后没有对相关二进制/动态库做strip；brpc的cpu profiler是基于gperftools实现的，也可以参考gperftools的文档。采样次数减少一般可以看做是当前函数的开销，对应到问题里就是start_thread本身的开销。 -- This is an automated message from the Apache Git Service.
