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. . <commandline> This happens for both a schema build and running a test.

Fortunately the HammerDB TPC-C/OLTP workload intentionally has a great deal of contention between threads and is therefore ideal for testing spin-locks. So to test I took a system with Skylake CPUs and all storage on a P4800X SSD. In the recent MySQL 8.0.16 model name : Intel(R) Xeon(R) Platinum 8180 CPU @ 2.50GHz. 23-generic x86_64).

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.

The way we measure this is through a ‘performance profile’ This simply means that we run a series of tests incrementally increasing the system load until we find the peak performance. Plotting these data points enables us to understand the scalability of the database software being tested on that system. and MySQL 8.0.25
