Slow PrestaShop store: speed it up before you lose sales
If your store takes more than three seconds to load, half of your visitors will leave. We measure performance, identify the real bottlenecks and speed up your store without breaking any features.
- Before-and-after performance audit: server response time, LCP and SQL queries
- Optimisation without a redesign or loss of functionality
- Fixing front-office and back-office performance issues
- Impartial hosting recommendations with no commission

The symptoms we check first
A systematic diagnosis, in the right order: we isolate the cause before changing a single file.
Temps de réponse serveur élevé
A TTFB of several seconds points to missing caching, an outdated PHP version or overloaded hosting.
Requêtes SQL en boucle
A poorly coded module can generate hundreds of queries per page.
Too many active modules
Too many modules, third-party scripts, and trackers slowing down every page load.
Unoptimised images
Visuels lourds, formats anciens, absence de chargement différé.
Extremely slow back office
Analytics data, oversized logs or uncleared database tables slowing down the back office.
Misconfigured cache
PrestaShop cache, OPcache, or CDN missing or misconfigured.

Questions fréquentes
Do you need to switch hosting providers to improve performance?
Not always. We first assess what is caused by the code and configuration. We only recommend changing hosting providers if hosting is genuinely the bottleneck.
Could optimisation break my website?
We create a backup and check each page individually, then test the entire checkout process before completing the work.
What performance gains can I expect?
For a store that has never been optimised, load times can often be reduced by half or even two-thirds. You will receive the before-and-after results.
Will this improve SEO?
Yes. Site speed directly affects Core Web Vitals and has a major impact on conversion rates.
