We Cut Blocking Time by 92% – A Story Starring useTransition
- The article shares a story of resolving a major performance issue in a project leading to a 92% reduction in blocking time and a 60% decrease in API calls.
- Challenges included sluggish UI, slow renders, and excessive API calls in a complex tree-table structure.
- The solution involved breaking heavy dependencies, stopping recursive fetching, and decoupling renders to optimize performance.
- Issues like excessive API requests, slow re-rendering, and state loss during global search were addressed and optimized.
- By redesigning the data fetching approach to consolidate requests, the performance significantly improved with reduced network overhead.
- To address laggy UI on URL changes, the dependency on URL changes was removed, transitioning to useTransition for non-blocking updates.
- The architectural shift emphasized isolating states, batch requests, and breaking heavy renders for improved performance.
- Lessons learned included the importance of architectural shifts for significant performance enhancements.
- This optimization story highlights that looking from a higher architectural viewpoint can lead to substantial improvements beyond mere micro-optimizations.
- The use of useTransition and isolated state changes led to substantial performance gains with small rerenders in less than 50ms.
