About Speed Log
Speed Log is an educational magazine dedicated to measuring and improving software speed. We believe that performance is a product feature, not an afterthought. Every article, tutorial, and discussion in this publication helps readers connect reliable measurements with practical changes that users can feel.
Our mission
Our mission is to make performance engineering approachable for developers, testers, site reliability engineers, and product teams. We explain how to choose meaningful metrics, design experiments, interpret results, and communicate trade-offs. The goal is not to chase a single number but to build habits that keep systems fast as they evolve.
What you will learn
Readers learn how to define service level objectives, select percentiles that reflect real journeys, and separate noise from regressions. We cover profiling techniques for CPU, memory, network, and storage, along with methods for reproducing bottlenecks in a safe environment. You will also find guidance on load testing, capacity planning, caching, database tuning, and front-end rendering budgets.
How we work
Our editorial process favors evidence over hype. We test examples on realistic workloads, document assumptions, and show how to verify improvements with repeatable measurements. When a technique has limits, we explain them. When a tool changes, we update the guidance so readers can make informed decisions.
For every team
Whether you maintain a small service or a global platform, Speed Log offers a path from curiosity to confidence. Start with the fundamentals, join the forum to compare notes, and share your own case studies. Together we can make software faster, more resilient, and more respectful of users’ time.
