 ## Test overview
 
-This test aims at comparing the TPC-H 100GB performance of TiDB v5.1 in the MPP mode with that of Greenplum and Apache Spark, two mainstream analytics engines, in their latest versions. The test result shows that the performance of TiDB v5.1 in the MPP mode is two to three times faster than that of the other two solutions under TPC-H workload.
