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

Modern servers operate with terabytes of RAM, and by default, processors work with virtual memory address translation for each 4KB page. OS maintains a huge list of allocated and free pages to make slow but reliable address translation from virtual to physical. Huge pages make PostgreSQL faster; can we implement it in Kubernetes?

HammerDB is a software application for database benchmarking. It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking.

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.
