![TPC-H Query Result](../media/tpch-query-result-v2.png)

It should be noted that:

- In the diagram above, the red bars represent the query results of Release 2.1 and the blue bars represent the query results of Release 2.0. The y-axis represents the processing time of queries in seconds, the shorter the faster.
- The result of Query 15 is not displayed because VIEW is currently not supported in either TiDB 2.1 or 2.0.
- The result of Query 5 is not displayed because no result is returned during a long period of time caused by the Join Order issue.
