Monitoring Browser Memory Usage

Browsers manage the memory used by web pages automatically without user interaction. Sematext Experience allows monitoring the memory usage for your web pages to identify issues, regressions, and give you an estimate of the memory needed by your applications.

Memory Usage Overview

Use Cases

There are many use cases where having insight into the browser's memory usage can be crucial to identify and fix problems as soon as possible. Those include:

  • Identifying memory leaks in Single Page Applications
  • A/B testing of memory usage between different application versions
  • Measuring memory impact of new features or optimizations done to the application code
  • Statistical analysis of memory usage across the web application

Measurements

Sematext Experience Browser SDK uses the Memory Measure API to measure browser memory usage when your web application is loaded and continues to measure the memory throughout the user session. This allows for memory measurements across pages and sessions. It even shows the per-session memory usage that individual users of your applications are experiencing.

At the moment, the only web browser that supports memory usage measurements is Chrome. The memory usage measurement feature was under Chrome Origin Trials until 13th January 2021 and is available to all users starting with Chrome 89.
