The Busy Developer's SSR Checklist: 7 Actionable Fixes for Faster Loads
You deploy a new server-rendered page, and the first load feels snappy in local dev. Then real users hit it—and the Time to First Byte (TTFB) balloons to three seconds. The server is struggling, the bundle is bloated, and the cache strategy is missing. This scenario is common, but it's also fixable without a full rewrite.

We'll walk through seven targeted fixes that address the most frequent SSR slowdowns, with concrete steps and trade-offs. 1.
