We can make a significant impact on performance and optimization by sharing responsibility across our organization, having the right information available to the right people, and using easily comprehensible metrics. A small team of engineers improved the load time of Intercom's website from 4.5 seconds to below 1 second through compression, delay loading non-critical items, caching, and monitoring page load times. By making performance metrics available to a wider audience, we can encourage care and responsibility for optimization across our organization, leading to better visibility and even better performance.
