In a new post on the Microsoft Edge blog, the browser’s Principal PM Lead Kim Denny has outlined how the company made it faster and more efficient over the past few months. To help users perform their tasks as quickly as possible, the team rolled out Profile-Guided Optimizations (PGOs) in Edge 81 Stable Channel and Link-Time Optimizations (LTOs) in Edge 83 back in March.
PGOs prioritize the most important parts of the code, while LTOs optimize memory usage. The two techniques apparently improved Edge’s speed by as much as 13 percent compared to previous versions, based on Speedometer 2.0 benchmark. Microsoft also introduced improvements to the browser’s scroll animation and enhanced how scrolling looks, feels and reacts to your touch in general back in April. Denny says those changes make Edge feel smoother and more responsive.
