How to reduce TTFB

TTFB (Time to First Byte) is a crucial metric for measuring server responsiveness and page load times. A high TTFB can be detrimental to user experience, especially in server-side rendered applications like Next.js. To reduce TTFB, developers need to identify the root cause of the slowdown using tools such as tracing. Tracing helps visualize the entire process from client-side to server-side and pinpoint specific functions causing delays. By integrating Sentry's automatic instrumentation and custom spans, developers can optimize their code and improve TTFB performance.
