Running in the web service CLI we can see that the command output is returned to the user, however the virtual user output is no longer returned and instead a jobid is given./hammerdbws. Running a Test. The following script is also recognisable as a valid CLI script with the addition of jobs commands to retrieve the test output.

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 already has 2 interfaces with which to interface with the commands to build and test databases using the GUI interface or CLI. The following test script shows how this interaction can be done also including deliberate errors to demonstrate error handling. From HammerDB version 3.2 hammerdbws HammerDB Web Service v3.2

The SE toolkit was fast, had no memory leaks (monitoring scripts could run for years) and let me implement lots of cool performance monitoring ideas. Allan also introduced me to Richard McDougall, who had worked with Allan for Sun Australia, and Richard visited for a rotation to build some monitoring tools.

The TPC publishes an official Docker image on Docker Hub to enable the rapid deployment and testing of databases with HammerDB. This image includes example scripts to build schemas and test your databases with a single command. Our Linux test system is running a MariaDB 10.10 Our Linux test system is running a MariaDB 10.10

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

To do this, we are going to rewrite HammerDB in Python and run a series of tests on a 2 socket Intel(R) Xeon(R) Platinum 8280L server to see how and why Tcl is 700% faster than Python for database benchmarking*.

This post complements the previous best practice guides this time with the focus on MySQL and MariaDB and achieving top levels of performance with the HammerDB MySQL TPC-C test. InnoDB is the storage engine that will deliver the best OLTP throughput and should be chosen for this test. . HammerDB difference from Sysbench.
