PrestaShop performance optimization (speed, CWV, database)

A slow store loses customers and Google rankings. You get bottleneck diagnosis (hosting, MySQL, cache, modules, front-end), fixes and measured results. The goal: clearly shorter load times, better stability and improved Core Web Vitals.

The problem

A slow PrestaShop store is one of the most common eCommerce problems. Typical symptoms: pages take 4–8 seconds to load, the back-office is sluggish, product imports take hours, and customers abandon their cart before checkout. The causes vary: unsuitable hosting (slow disk, insufficient RAM), unoptimized MySQL database (missing indexes, stale data in tables), no cache (Redis, OPcache), excessive modules generating hundreds of SQL queries, unoptimized front-end (large images, render-blocking CSS/JS). Each of these problems slows the store, but they often occur simultaneously.

Scope of work

  • Performance audit: measuring load times, SQL query analysis (slow query log), PHP profiling, hosting IOPS test
  • MySQL tuning: optimizing InnoDB and memory settings, adding missing indexes, cleaning tables
  • Cache deployment: Redis as object and session cache, OPcache for PHP, Smarty cache configuration
  • Front-end optimization: image compression (WebP), lazy loading, CSS/JS minification, eliminating render-blocking resources
  • Module audit: identifying and removing/replacing modules that slow down the store
  • CDN configuration for static assets (images, CSS, JS, fonts)

What you get

  • Performance audit report: list of bottlenecks with priorities and estimated impact on load time
  • Optimized server and MySQL configuration tuned for the store's traffic load
  • Deployed and configured cache (Redis + OPcache) with measurable response time improvement
  • Optimized front-end with improved Core Web Vitals scores (LCP, INP, CLS)
  • Before/after measurements with specific numbers: load time, Lighthouse score, TTFB

Frequently Asked Questions

How much can you speed up my PrestaShop store?

It depends on the store's current state. After the audit and implementation work, you can usually expect a clear improvement in load time, stability and Core Web Vitals. You get a more precise estimate after the initial audit.

Does the optimization require changing hosting?

Not always, but hosting is often one of the key bottlenecks (slow disk, insufficient RAM for MySQL). The audit reveals whether your current hosting is sufficient — and if not, you get a specific server recommendation and migration assistance.

How is the performance improvement measured?

Before and after measurements cover: page load time (TTFB, FCP, LCP), Lighthouse/PageSpeed Insights score, Core Web Vitals and server response time. You receive a report with concrete numbers confirming the improvement.

Won't the optimization break something in the store?

Every change is tested on a staging environment before being deployed to production. A rollback plan is in place for unexpected issues. Changes are deployed in stages to make it easy to identify any regressions.
