Standard throughput benchmarks
The Transaction Processing Performance Council (TPC) provides standard benchmarks that allow reasonable throughput comparisons across hardware configurations and database servers. HCL is an active member in good standing of the TPC.
- TPC-A
This benchmark is used for simple online transaction-processing (OLTP) comparisons. It characterizes the performance of a simple transaction-processing system, emphasizing update-intensive services. TPC-A simulates a workload that consists of multiple user sessions connected over a network with significant disk I/O activity.
- TPC-B
This benchmark is used for stress-testing peak database throughput. It uses the same transaction load as TPC-A but removes any networking and interactive operations to provide a best-case throughput measurement.
- TPC-C
This benchmark is used for complex OLTP applications. It is derived from TPC-A and uses a mix of updates, read-only transactions, batch operations, transaction rollback requests, resource contentions, and other types of operations on a complex database to provide a better representation of typical workloads.
- TPC-D
This benchmark measures query-processing power in terms of completion times for very large queries. TPC-D is a decision-support benchmark built around a set of typical business questions phrased as SQL queries against large databases (in the gigabyte or terabyte range).
Because every database application has its own particular workload, you cannot use TPC benchmarks to predict the throughput for your application. The actual throughput that you achieve depends largely on your application.
