How I Reduced Website Latency by Optimizing the Right Things
I recently spent some time optimizing one of my websites, and honestly, the biggest improvements didn’t come from some fancy optimization trick. It came from measuring everything first. I started looking at the actual request timings: DNS lookup TCP connection TLS handshake Time to First Byte (TTFB) Total response time Then I worked through the bottlenecks one by one. Some of the things that…
In a recent effort to improve website performance, the author discovered that the key to significant improvements came from a methodical approach of measuring and addressing actual bottlenecks rather than relying on flashy optimization techniques. The process began with analyzing various request timings such as DNS lookup, TCP connection, TLS handshake, Time to First Byte (TTFB), and total response time.
By focusing on reducing unnecessary server-side work, improving caching, streamlining API requests, keeping database queries lean, minimizing network round trips, fine-tuning server configurations, and employing CDN or edge caching where appropriate, the author managed to make the first request reach users more swiftly. Importantly, the author learned that a website's perceived speed can vary greatly depending on the user's location, highlighting the importance of testing from diverse geographies.
The primary objective wasn't to chase a perfect Lighthouse score but to prioritize making the initial request as quick as possible for the user. Remarkably, modest improvements across multiple layers collectively resulted in a substantial difference. The author remains open to continued experimentation, emphasizing that performance optimization is primarily about pinpointing the true bottlenecks rather than making unfounded assumptions.
