⚡ Poor TTFB indicates that your servers aren’t responding quickly enough, which can cause cascading performance issues for the entire page-loading process.
Here’s how to ensure a good TTFB measurement:
🔹 upgrade your hosting
🔹 use a CDN
🔹 reduce DNS lookup time
🔹 always default to server-rendered HTML -
