MongoDB Performance Resources

Alex Podelko

As I started to work for MongoDB, I started to get questions about MongoDB performance. We do have a lot of great resources that can help with MongoDB performance. First of all, it is MongoDB and Atlas documentation: Performance , Monitoring , and Query Optimization.

Performance Testing at MongoDB

Alex Podelko

MongoDB has the most advanced continuous performance testing I know about. MongoDB shared a lot of information on how we do performance testing and even open sourced some parts of it. Continuous performance testing is built on the top of Evergreen.

The Future of Performance Testing

Alex Podelko

While there are still quite a lot of cases where it is still applicable, it needs to evolve into more sophisticated processes tightly integrated with development and other parts of performance engineering. First of all, integrating into agile development (shift-left / continuous performance testing) and integrating into performance information loop with production (shift-right) to form a holistic performance view.

Performance Budgets, Pragmatically

CSS Wizardry

One of the key tools that performance engineers have at their disposal is the Performance Budget: it helps us—or, more importantly, our clients—ensure that any performance-focused work is monitored and maintained after we’ve gone. Example Performance Budgets.

Removing the Roadblock to Continuous Performance Testing


Continuous performance testing makes total sense. performance testing load testing continuous testing ci/cd pipeline smoke testingYou can’t afford to have a new feature, update, or bug fix brings you two steps forward and three steps back.

CSS and Network Performance

CSS Wizardry

Let me address that by combining my two favourite topics: CSS and performance. Broadly speaking, this is why CSS is so key to performance: A browser can’t render a page until it has built the Render Tree; the Render Tree is the combined result of the DOM and the CSSOM; the DOM is HTML plus any blocking JavaScript that needs to act upon it; the CSSOM is all CSS rules applied against the DOM; it’s easy to make JavaScript non-blocking with async and defer.
