If you are not already familiar with the programming languages that HammerDB uses, then this earlier post serves as an ideal introduction to what makes up the highest performing GIL free database benchmarking application. The build has been tested on x64 Red Hat 8.X The build has been tested on x64 Windows 10 and 11. HammerDB-4.4-Linux.tar.gz

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 the PAUSE instruction is an optimization over NOP when a thread is waiting to acquire a lock and is particularly important in spin-locks on x86 CPUs for power and performance.

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. HammerDB difference from Sysbench.

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.

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. We use stored procedures because, as the introductory post shows, using single SQL statements turns our database benchmark into a network test).

Back in the Dim And Distant Past of 2003 I even co-led an open source project that brought some at-the-time interesting innovations to this area. You tell it where to get some source code from, give it a bunch of scripts to run in a shell environment (build, package, test, etc.), Build + Test ? It’s cheap, simple, does the job.

That was the provocative thesis of a much-talked-about article from 2003 in the Harvard Business Review by the US publicist Nicolas Carr. The reason is that the success and speed and frequency of these experiments depend on the performance of IT development, and at the same time on the relevance of the solutions for business operations.

This wording is intentional: how work is performed reduces the probability of failure. If the governance imperative is to understand that results are being achieved in addition to knowing how they are being achieved, we must consider another key point: what must we do to know with certainty how work is being performed?
