You should already be aware that due to the Python GIL impacting multithreading performance it is not possible to drive a high-performance database workload directly from Python. Why Tcl is 700% faster than Python for database benchmarking.

cloud based usage led to the development of a HammerDB HTTP based web service interface with output data stored in a SQLite database repository. ws_port defines on which port to start the HTTP service, whilst sqlite_db sets the location of the SQLite repository database.

HammerDB Variable or Step Workloads are an advanced testing feature that enables you to automatically vary the load on the database over a period of time. 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.

Another big jump, but now it was my job to run benchmarks in the lab, and write white papers that explained the new products to the world, as they were launched. I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R.

HammerDB already has 2 interfaces with which to interface with the commands to build and test databases using the GUI interface or CLI. From HammerDB version 3.2 there is an additional interface that enables HammerDB to run as Web Service. see the documentation for setting the port). . $./hammerdbws hammerdbws HammerDB Web Service v3.2

However if you have downloaded the source code and are looking to add features or make modifications such as adding new databases you may be wondering once you have the source code where to start. However HammerDB will not be able to connect to a database yet and the librarycheck command included with the CLI gives an indication why.

Similarly for this guide MySQL can be swapped for a mySQL based databases such as MariaDB. As is also the case this limitation is at the database level (especially the storage engine) rather than the hardware level. As is exactly the same with PostgreSQL for system choice a 2 socket system is optimal for MySQL OLTP performance.

Besides that, the numbers can vary greatly depending on many factors, so our goal here is just to provide a few benchmarks that give some sense of the magnitude of potential improvements.
