> 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.
