In order to better grasp the performance of database in practical application, we add a module to count the time-consuming of each operation. This module can statistic the avg time-consuming of each operation and the proportion of each operation fall into a time range.A output example is in below. This module uses asynchronous operation to reduce the impact on the normal speed of the database.The queue size is controlled by a param in iotdb-engine.properties, which is 'performance_stat_memory_in_kb'. The  output is in  log_measure.log file.
