One of the most important concepts in analysing database performance is that of understanding scalability. When a system ‘scales’ it is able to deliver higher levels of performance proportional to the system resources available to it. In this example, we will compare MySQL 5.7.33 and MySQL 8.0.25 and MySQL 5.7.33.

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

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. lc_messages = 'en_GB.UTF-8' # locale for system error message.

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.

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.

Breakaway opportunities tend also to be highly sensitive to non-functional requirements, such as performance, scalability and security. They create all these systems and processes – and then end up with a very small percentage of people who are supposed to solve complex problems, while the other 98% of people just execute.
