TiDB TPC-C Performance Test Report -- v5.1.0 vs. v5.0.2

Test overview

This test aims to compare the TPC-H performance of TiDB v5.1.0 and TiDB v5.0.2 in the online analytical processing (OLAP) scenario. The results show that compared with v5.0.2, the TPC-C performance of v5.1.0 is improved by 2.8%.

Test plan

  1. Deploy TiDB v5.1.0 and v5.0.2 using TiUP.
  2. Create a database named tpcc: create database tpcc;.
  3. Use BenchmarkSQL to import the TPC-C 5000 Warehouse data: tiup bench tpcc prepare --warehouse 5000 --db tpcc -H 127.0.0.1 -p 4000.
  4. Execute the tiup bench tpcc run -U root --db tpcc --host 127.0.0.1 --port 4000 --time 300s --warehouses 5000 --threads {{thread}} command to perform stress tests on TiDB via HAProxy.
  5. Extract the tpmC data of New Order from the result.

Test result

Compared with v5.0.2, the TPC-C performance of v5.1.0 is improved by 2.8%.
