There is only so much control you can exert over your app's performance, but controlling the code is arguably most important. Sentry Performance provides code-level insights to help resolve performance bottlenecks. Query Insights allows users to identify slow database queries and their impact on API endpoints, enabling them to fix issues quickly. By analyzing query metrics, impacted API endpoints, and transaction details, developers can pinpoint performance regressions and make targeted updates to improve overall application performance.
