Python is a popular programming language, especially for beginners, and consequently we see it occurring in places where it just shouldn’t be used, such as database benchmarking. We use stored procedures because, as the introductory post shows, using single SQL statements turns our database benchmark into a network test).
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.

Note that by default the build script will query the number of CPUs on the system that HammerDB is running and configure 5X this number for the number of warehouses to build. If HammerDB is running on a separate system from the database under test then you should modify this value accordingly. scripts/tcl/maria/tprocc/maria_tprocc.sh

on Myths and Legends of High Performance Computing — it’s a somewhat light-hearted look at some of the same issues by the leader of the team that built the Fugaku system I mention below. HPCG is led by Japan’s RIKEN Fugaku system at 16 petaflops, which is 3% of it’s peak capacity. Next generation architectures will use CXL3.0
introduces more lightweight database specific Docker Images, so if you only want to run benchmarks against a specific database you can go from having no benchmarking environment to reviewing your results in as little as 3 commands. How to deploy HammerDB CLI fast with Docker HammerDB v4.7 scripts/tcl/postgres/tprocc/pg_tprocc.sh
this web interface has been enhanced to add command line functionality to the service as well as extending the ability to query the database of configuration, results and timing data to be returned in JSON format, enabling a long-term repository of HammerDB benchmark data for integrating HammerDB into service based cloud environments.

HammerDB will rely on the system installed Python interpreter and at a specific version as described in the following table. Copyright (C) 2003-2022 Steve Shaw. Copyright (C) 2003-2022 Steve Shaw. Why Tcl is 700% faster than Python for database benchmarking. From version v4.6 Python Version Dependency. HammerDB CLI v4.6.
Most of this article represents an overview of the results published by retailers and researchers who built practical decision making and optimization systems combining abstract economic models with data mining methods. The most typical use cases for this problem are recommender systems, personalized search results ranking, and targeted ads.

As with the previous guides as an Intel employee (#IAMINTEL) the examples are taken from a MySQL 8 on Linux on Intel system and the approach is the same for whatever system you are testing although some of the settings you see may be different. System Setup: CPU, Memory and I/O Configuration. HammerDB difference from Sysbench.
This article Threads Done Right… With Tcl gives an excellent overview of these capabilities and it should be clear that to build a scalable benchmarking tool this thread performance and scalability is key. The agent directory contains the agent code to be run on the system under test to gather the CPU utilisation information.
Photo by Adrian I spent six years at Cambridge Consultants, building some interesting systems, managing our Sun workstations and learning a lot, but by then Sun had opened a sales office across the street, and I wanted to find out what they were going to release next, before everyone else.
