HammerDB is a load testing and benchmarking application for relational databases. All the databases that HammerDB tests implement a form of MVCC (multi-version concurrency control). On high-performance multi-core systems all the supported databases can return performance in the many millions of transactions per minute.

This blog was originally published in Sept 2021 and was updated in November 2023. Following the series of blogs started by Peter Zaitsev in Installing MySQL with Docker , on deploying Docker containers running open source databases, in this article, I’ll demonstrate how to install and run PostgreSQL using Docker.

To learn how to solve these challenges, we sat down with Dynatrace technical project managers Michal Franszak and Michal Nalezinski at Perform 2021. Without the overhead of establishing and maintaining on-premises servers, these systems save resources. The DS database had been reconfigured, which impacted 400 users.

Unfortunately, using certain open source database software as part of an HA architecture can present significant challenges. This blog highlights considerations for keeping your own PostgreSQL databases highly available and healthy. The same changes made in the primary database are made in the replicas.

One of the most important concepts in analysing database performance is that of understanding scalability. Plotting these data points enables us to understand the scalability of the database software being tested on that system. Then we can run an interactive workload for a single Virtual User as follows for MySQL 8.0.25.

Clearly, the “first client rules all” approach needed to be replaced with a solution in which the game state lives on the server. Martin Grubinger.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. top(1) showed that only the Cassandra database was consuming CPU. This server is spending about a third of its CPU cycles just checking the time!

We shall also see how decisions are made in an enterprise and why cross-browser testing is the most important thing in 2021 to sustain a healthy business. Considering this requirement and the website load, enterprises generally set up multiple servers and machines that can talk to each other through a network. A platform.

Teams achieving this level of discipline about performance begin to eliminate variance from their lab data by running tests in "less noisy" environments than somewhere like a developer's laptop, a shared server, or a VM with underlying system variance. Teams can quickly regress from Level 4 maturity through turnover.
