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

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 doesn’t publish competitive database benchmarks, instead we always encourage people to be better informed by running their own. So over at Phoronix some database benchmarks were published showing PostgreSQL 12 Performance With AMD EPYC 7742 vs. Intel Xeon Platinum 8280 Benchmarks . uname -a Linux ubuntu19 5.3.0-rc3-custom

As (C) looked like a kernel rebuild, I started with (D) and (E). ## 5. There's also a test and println() in the loop to, hopefully, convince the compiler not to optimize-out an otherwise empty loop. This will slow this test a little.) I also rewrote this in C and called gettimeofday(2) directly: $ cat gettimeofdaybench.c.

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. . order by c.
