Modern stack: why a Next.js site is faster than WordPress
Site speed is not a matter of developer taste. It affects conversion and rankings directly, and architecture decides it more than any after-the-fact optimisation.
The architectural difference
A classic CMS rebuilds the page on every request: start the interpreter, query the database, apply theme and plugins, return HTML. Every step adds latency, and much more under load.
The modern approach serves a pre-rendered page from a CDN and loads dynamic parts separately, so nothing has to be computed at request time.
Where the gain comes from
Pre-rendering, delivery from a nearby edge location, automatic image optimisation into modern formats, and shipping only the JavaScript a page needs.
For an Uzbek audience this matters more than average: much of the traffic is mobile on imperfect connections, where an instant page converts noticeably better.
When not to switch
If your CMS site performs acceptably and does its job, rewriting for the technology is wasted budget — caching, plugin cleanup and image optimisation often recover most of the gap.
Also honest: a modern stack needs a prepared editing interface, otherwise content changes go back through a developer. Plan for it, or stay with the familiar CMS.
