BiteTheDDDDt opened a new issue #6458:
URL: https://github.com/apache/incubator-doris/issues/6458


   **Describe the bug**
   `SCOPED_RAW_TIMER` can be used to calculate the time usage in the life 
cycle. 
   It will only update the time when it is destruct.
   I found it was used incorrectly in some places.
   ```cpp
       std::vector<scoped_refptr<Thread>> threads(1000);
       {
           int64_t thread_creation_ns = 0;
           SCOPED_RAW_TIMER(&thread_creation_ns);
           for (auto& t : threads) {
               Status status = Thread::create("test", "TestCallOnExit", 
SleepFor,
                                              MonoDelta::FromSeconds(0), &t);
               ASSERT_TRUE(status.ok());
           }
           std::cout << "create 1000 threads use:" << thread_creation_ns << 
"ns" << std::endl;
       }
   ```
   Like here, the output result will always be 0.
