+# Introduction
 
 taosBenchmark (formerly taosdemo ) is a tool for testing the performance of TDengine products. taosBenchmark can test the performance of TDengine's insert, query, and subscription functions and simulate large amounts of data generated by many devices. taosBenchmark can be configured to generate user defined databases, supertables, subtables, and the time series data to populate these for performance benchmarking. taosBenchmark is highly configurable and some of the configurations include the time interval for inserting data, the number of working threads and the capability to insert disordered data. The installer provides taosdemo as a soft link to taosBenchmark for compatibility with past users.

 - **name** : The name of the column, if used together with count, e.g. "name": "current", "count":3, then the names of the 3 columns are current, current_2. current_3.
 
-- **min**: The minimum value of the column/label of the data type.
+- **min**: The minimum value of the column/label of the data type. The generated value will equal or large than the minimum value.
 
-- **max**: The maximum value of the column/label of the data type.
+- **max**: The maximum value of the column/label of the data type. The generated value will less than the maxium value.
 
 - **values**: The value field of the nchar/binary column/label, which will be chosen randomly from the values.
