Test plan

1. Deploy TiDB v4.0 and v3.0 using TiUP.

2. Use BenchmarkSQL to import the TPC-C 5000 Warehouse data.

   1. Compile BenchmarkSQL:

    ```bash
    git clone https://github.com/pingcap/benchmarksql && cd benchmarksql && ant
    ```

2. Enter the `run` directory, edit the `props.mysql` file according to the actual situation, and modify the `conn`, `warehouses`, `loadWorkers`, `terminals`, and `runMins` configuration items.

3. Execute the `runSQL.sh ./props.mysql sql.mysql/tableCreates.sql` command.

4. Execute the `runSQL.sh ./props.mysql sql.mysql/indexCreates.sql` command.

5. Run MySQL client and execute the `analyze table` statement on every table.

3. Execute the runBenchmark.sh ./props.mysql command.

4. Extract the tpmC data of New Order from the result.

Test result

According to the test statistics, the TPC-C performance of TiDB v4.0 has increased by 50% compared with that of TiDB v3.0.
