Microsoft has tweaked the Microsoft Edge sleeping tabs feature to improve the web browser's overall responsiveness and performance.
"Beginning in Microsoft Edge 100, we've updated sleeping tabs to enable pages that are sharing a browsing instance with another page to now go to sleep," the Microsoft Edge Team said earlier this week.
"With this change, 8% more tabs on average will sleep, saving you even more resources! On average, each sleeping tab saves 85% of memory and 99% CPU for Microsoft Edge.".
"Sleeping tabs will automatically force inactive background tabs to"go to sleep" automatically, " releasing system resources after a pre-defined time.
"Sleeping tabs builds upon the core of Chromium's 'freezing' technology," Microsoft Senior Program Manager Eleanor Huynh explained when the feature was announced.
Based on performance tests across roughly 13000 devices, Microsoft says sleeping tabs reduce memory usage by 32% on average and, in most cases, it will also lead to approximately 37% lower CPU usage.
