What commenters say

• Synthetic benchmarks like Speedometer may not accurately reflect real-world performance, but being fast is still preferable to being slow.
• Firefox's performance improvements are the result of significant investment and organizational focus on performance targets.
• Some users prioritize factors other than speed, such as security and privacy, when choosing a browser.
• The Speedometer benchmark is a good measure of 'snappiness' and UI updates, but may not be representative of compute-bound or I/O-bound tasks.
• Firefox's history pruning feature can be a problem for users who need to access old browsing history.
• Clearing the browser profile and managing cache can significantly improve performance, regardless of the browser used.
• The trade-off between performance and features like history retention is a complex issue, with some users willing to sacrifice speed for functionality.
• Different browsers have different strengths and weaknesses, and the choice of browser depends on individual priorities and needs.
