Regardless of whether the computing platform to be evaluated is on-prem, containerized, virtualized, or in the cloud, it is crucial to consider several essential factors. Benchmarking the target Two of the more popular database benchmarks for MySQL are HammerDB and sysbench. For storage, FIO is generally used. 4.22 %usr 38.40

The use case is the TPC-C benchmark but executed not on a high-end server but on a lower-spec virtual machine that is I/O limited like for example, with AWS EBS volumes. I decided to use a virtual machine with two CPU cores, four GB of memory, and storage limited to a maximum of 1000 IOPs of 16KB. . <iotune>

In particular, after a running a test it would be ideal to have a repository where we could verify the configuration of the workload that was run, the results and any timing or transaction count data generated to bring all the log output into a central location. HammerDB v4.6 does this with the “jobs” command. HammerDB CLI v4.6

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 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.

HammerDB is a load testing and benchmarking application for relational databases. This helps to minimise locking allowing multiple sessions to access the same data at the same time. However, it is crucial that the benchmarking application does not have inherent bottlenecks that artificially limits the scalability of the database.

In this example, we will use the CLI to run TPROC-C on a MariaDB database to illustrate the concepts. This setting is exactly how it sounds and simulates the delay a real user would have in inputting data i.e. keying time and reading the results returned i.e. thinking time.

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”
