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. As is exactly the same with PostgreSQL for system choice a 2 socket system is optimal for MySQL OLTP performance. order by c.

adds full support for MariaDB in both the GUI as shown: And in the CLI as a separate database from MySQL, this post describes a setup and test for MariaDB using the CLI on Linux as an example running the TPROC-C workload. A future blog post on performance profiles will explain why this is a good first test on which to baseline other changes).

This post addresses both questions to illustrate exactly why HammerDB is written in Tcl and why using Python to benchmark a database can result in poor performance and misleading results. Surely any language will do? For this example, we are going to use PostgreSQL stored procedures in PostgreSQL 14.1. usr/local/bin/tclsh8.6

This post gives a HOWTO guide on system configuration for achieving top levels of performance with the HammerDB PostgreSQL TPC-C test. Firstly for system choice a 2 socket system is optimal for PostgreSQL OLTP performance at the time of writing. Make sure that your CPU is configured for optimal performance.

I became the Sun UK local specialist in performance and hardware, and as Sun transitioned from a desktop workstation company to sell high end multiprocessor servers I was helping customers find and fix scalability problems. Rich became co-author of the second edition of the Sun Performance Tuning book, to describe how it worked.
