Speeding up the site where users are actually waiting
A lab score does not tell the whole story. We combine synthetic measurements, field data where it exists and observation of the technical chain.

Every slowdown has its own cause
An oversized hero image, a slow SQL query, a third-party script or a misconfigured cache are not fixed the same way.
The dominant cause first
We look for the dominant cause before applying generic optimisations.
A method before optimisations
We compare lab measurements (Lighthouse, PageSpeed Insights) with field data from real visits when it exists, then work our way along the chain: server, database, cache, page weight, scripts. The dominant cause is fixed first, because it often explains most of the slowness.
The causes we come across most often
- images that are too heavy or lack dimensions, delaying display and making the page jump;
- third-party scripts (chat, ads, analytics) loaded before the content;
- SQL queries without indexes on tables that have grown;
- caching that is missing or misconfigured;
- a theme or plugins that load everything on every page;
- hosting that is undersized for the actual traffic.
This website as an example
The auxioma.eu home page weighs around 5 KB of compressed HTML, with a stylesheet of about 20 KB and a main script of a few kilobytes. The 3D scene is loaded only once the page is displayed, and the chat loads only on click. Content therefore never depends on heavy JavaScript: this is the principle we apply to our clients’ websites.
Frequently asked questions
Should we aim for 100 on PageSpeed?
No. The lab score helps with diagnosis, but what counts is the experience of real visitors, measured by Core Web Vitals. A perfect score achieved by removing useful features is not a good result.
Is a CDN enough?
A CDN speeds up file delivery and can cache pages, but it fixes neither a slow query nor an overly heavy page. It is a complement, not a cure.
