Test Method
This section describes BenchmarkSQL performance tests and test reports for GaussDB.
BenchmarkSQL is a JDBC benchmark test tool and runs a TPC-C. It can be used for many databases, such as PostgreSQL, Oracle, and MySQL.
TPC-C is a specification for online transaction processing (OLTP) systems. Generally, such systems are called service processing systems. Almost all mainstream international vendors that provide software and hardware platforms in the OLTP market have released TPC-C test results. With the development of computer technologies, these test results are continuously updated.
Test Environments
- Site: Huawei Cloud.
- Instance type: distributed, primary/standby
- Specifications: 16 vCPUs | 128 GB and 32 vCPUs | 256 GB.
- Cluster scale: for a distributed instance: 3 CNs, 3 shards, and 3 replicas; for a primary/standby instance: 1 primary node and 2 standby nodes.
Test Method
- Change the connection configuration.
- Change key parameters.
//Connection configuration conn=jdbc:postgresql://127.0.0.1:8000/postgres?autoBalance=true //Username user=**** //Password password=**** //Number of warehouses warehouses=1000 //Number of concurrent loadWorkers that are used to import data loadWorkers=10 //Number of concurrent terminals terminals=2048 //Running duration runMins=30
- Import data.
./runDatabaseBuild.sh props.pg
- Run the TPC-C test.
./runBenchmark.sh props.pg

Test Metrics
According to the Transaction Processing Performance Council (TPC), tpmC describes the number of new orders processed per minute while the system is performing four types of transactions: payment operations, order status queries, deliveries, and stock status queries. The response time of all transactions and the proportion of each type of transactions must meet the requirements of the TPC-C test specifications. In this case, the larger the tpmC value is, the higher the online transaction processing (OLTP) of the system is.
