HammerDB uses stored procedures to achieve maximum throughput when benchmarking your database. HammerDB has always used stored procedures as a design decision because the original benchmark was implemented as close as possible to the example workload in the TPC-C specification that uses stored procedures. On MySQL, we saw a 1.5X

Arguably, the most common beginning errors with database benchmarking is for a user to select a single point of utilisation (usually overconfigured) and then extrapolate conclusions about system performance from this single point. automates this practice by introducing the concept of performance profiles for TPROC-C workloads.

HammerDB is a software application for database benchmarking. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. The Transaction Processing Performance Council (TPC) was founded to bring standards to database benchmarking, and the history of the TPC can be found here.

In production environments, it is observed that a large value for shared_buffer gives really good performance, though you should always benchmark to find the right balance. For testing purposes, let’s increase this to 256MB and see if there is any impact on cost. That said, you obviously do not want to reserve all RAM for PostgreSQL.

A frequently asked question with HammerDB is when a user is using the TPROC-C workload to test database failure and failover scenarios, by deliberately killing connections or shutting down the database during a workload and then restarting it. Is a TPROC-C workload valid if you have restarted the database?

When taking this approach you would not focus on the test result but instead monitor the databases ability to cope with the variation in demand and transaction response times.
