Stores we have built and run
Magento performance optimization finds what slows your store for real visitors and fixes it: heavy frontend JavaScript, missing full-page cache, oversized images and slow database queries. We measure Core Web Vitals (LCP, INP and CLS) from Google’s field data before and after, so you can see the change.
The targets we work to

Breeze, Hyvä or Luma?

|---|---|---|---|
| Approach | Default | Lighter Luma | New frontend |
| Extensions | Native | Mostly work | Need compat |
| Effort | – | Lower | Higher |
This site runs on Breeze. We work with both and recommend what fits your extensions and budget.

Measured on real visitors

- LCP: how fast the main content appears
- INP: how quickly the page responds

Questions before you book
Frequently asked questions
What are Core Web Vitals?
Google measures loading (LCP), responsiveness (INP) and visual stability (CLS) from real Chrome users. They are part of how Google evaluates page experience.
Should I switch to Hyvä or Breeze?
Breeze keeps your Luma-based theme and extensions with smaller changes. Hyvä is a new frontend that needs compatible modules. We compare both for your store.
How quickly will I see results?
Lab tests change immediately. Google field data is a 28-day rolling average, so the full effect shows in Search Console after about a month.
Is Varnish still needed with Breeze or Hyvä?
Yes. The theme makes pages lighter in the browser; Varnish makes the server answer faster. They solve different problems.
Will performance work cause downtime?
Most changes need no planned downtime. Everything is built and tested on staging, then released in an agreed window with a rollback path.
Do you need access to our server?
For server and cache tuning, yes, or we give your host a written list of changes. Frontend work only needs the code repository and a staging site.
