Magento Performance Audit
A technical deep dive into what’s slowing your store down and how to fix it
Magento Performance Audit identifies critical performance issues across your frontend, backend, infrastructure, and third-party extensions. Whether you're running Hyvä (yes, even blazing fast out-of-the-box Hyva Theme can have performance issues if not implemented correctly), Luma, or a headless setup, we’ll show you exactly where your site is lagging—and how to fix it. Let’s make your store fast, stable, and ready for scale.
Why Magento Performance Matters
Performance is tightly connected to how users experience your site and how your business performs as a result. Page speed directly impacts conversion rates, search engine visibility, and even operational efficiency. Magento is a powerful platform, but its flexibility means performance depends heavily on implementation.
Many Magento stores accumulate performance issues over time: theme bloat, poorly optimized customizations, unmonitored third-party extensions, or infrastructure that no longer fits the traffic profile. These don’t always show up in error logs, but they silently hurt customer experience and revenue.
A performance audit helps you:
- Understand what’s really slowing your store down
- Identify which optimizations will deliver the highest impact
- Avoid premature scaling or costly overengineering
- Plan future development or replatforming from a position of clarity
- Establish a baseline to measure performance improvements over time
This is especially critical before high-traffic periods, during rapid growth, or when migrating to a new frontend like Hyvä or a headless stack.
When you need Magento Performance Audit
- Your store feels slower than it should, but the cause isn’t obvious
- You’re planning for a peak season or a major traffic event
- You’ve recently added new features, modules, or integrations and noticed a performance drop
- You’ve outgrown your current infrastructure, or suspect that’s part of the problem
- You’re preparing for a redesign, replatform, or frontend switch (e.g., Hyvä, PWA, headless) and want to start with a clean performance baseline
- Your team needs concrete, prioritized recommendations—not vague performance tips or finger-pointing between vendors
What Our Magento Performance Audit Covers
Our full Magento Performance Audit goes far beyond automated tests. It’s a comprehensive, hands-on evaluation of your store’s speed, stability, scalability, and user experience—conducted by performance engineers, Magento developers, and QA specialists working together.
We combine advanced tooling (WebPageTest, Lighthouse, New Relic, custom profiling) with manual QA testing and behavioral analysis to uncover the real root causes of performance bottlenecks—not just surface metrics.
- 📈 Core Web Vitals (LCP, INP, CLS). Deep analysis of Google’s user experience metrics across Homepage, Product Page, Checkout, and Category templates using both lab and field data. We identify what specifically impacts each metric and how to improve it.
- ⚙️ Frontend Performance. Detailed breakdown of load time, JavaScript execution, render-blocking resources, font handling, critical CSS, and asset delivery strategy. We review real user traces to expose performance cliffs.
- 🔍 Manual QA-Based UX Testing. Our QA engineers manually test your store on desktop and mobile, uncovering functional bugs, broken elements, misaligned interactions, and UX friction not detected by automated tools.
- 🧱 Layout & Visual Stability. We flag layout shifts, delayed image rendering, and style reflows, which negatively affect CLS and perceived polish.
- 🚀 Caching & TTFB Optimization.We assess Time to First Byte (TTFB), server response patterns, Magento cache configuration (FPC, Redis/Varnish), and logic.
- 🧩 Third-Party & Extension Impact. Evaluation of third-party services, scripts, and Magento extensions that may block rendering, slow down checkout, or affect responsiveness. We also review SPOF (single points of failure) and suggest fallback strategies.
- 📷 Image & Media Optimization. In-depth review of file formats (WebP, SVG, AVIF), compression settings, lazy-loading logic, responsive image handling (srcset), and above-the-fold priorities.
- 📱 Mobile Performance & Usability. Hands-on review of tap targets, touch gestures, navigation patterns, mobile breakpoints, fixed headers/footers, and layout responsiveness.
- 🔐 Security & HTTPS Configuration. Scan for exposed admin URLs, missing security headers, mixed content, and insecure request handling. We also inspect caching behavior for sensitive data.
- 📊 Traffic Load & Scalability Readiness (Optional) Load testing under simulated high-traffic conditions. We analyze memory use, CPU load, and performance under concurrency to assess scaling potential.
| Area | What We Review |
|---|---|
| 📈 Core Web Vitals (LCP, INP, CLS) | Deep analysis of Google’s UX metrics across key templates (Homepage, PDP, PLP, Cart, Checkout) using both lab tools and field data. We identify the components affecting each metric and how to improve them. |
| ⚙️ Frontend Performance | Load time, blocking assets, JS execution, CSS delivery, font rendering, and DOM complexity. We use Lighthouse, WebPageTest, and browser trace analysis. |
| 🔍 Manual QA-Based UX Testing | QA specialists manually test key user flows (browse, add to cart, checkout) to uncover functional bugs, broken UI elements, and friction points not detectable by automated tools. |
| 🧱 Layout & Visual Stability | We flag layout shifts, image reflows, missing width/height attributes, and rendering glitches that impact CLS and perceived quality. |
| 📷 Image & Media Optimization | Review of image formats (WebP, AVIF, SVG), compression, responsive images, lazy loading behavior, and above-the-fold media priorities. |
| 📱 Mobile Performance & Usability | Mobile layout behavior, tap target sizing, responsive navigation, mobile header/footer rendering, and layout breakpoints across devices. |
| 🧩 Third-Party & Extension Impact | Identify performance issues caused by Magento extensions and third-party scripts. We flag render-blocking assets, checkout slowdowns, and single points of failure (SPOF). |
| 🔄 Magento Backend & Indexers | Review Magento indexer health, cron jobs, background task scheduling, and long-running processes that block admin or frontend responsiveness. |
| 🧠 Database Query Analysis | Identify slow queries, missing indexes, Magento ORM inefficiencies, and catalog-related DB stress that affect load times or CPU usage. |
| 🚀 Caching & TTFB Optimization | Audit of FPC, Redis/Varnish configuration, cache warming, block caching, and overall Time to First Byte (TTFB) performance. |
| 🛠️ Server & PHP Profiling | Inspect server software (Apache/Nginx), PHP-FPM settings, OPCache config, resource limits, and concurrency handling. |
| ⚖️ Traffic Load & Scalability (optional) | Load testing to simulate peak traffic conditions. We assess how your store handles concurrent requests, memory use, CPU limits, and error thresholds. |
| 🔐 Security & HTTPS Configuration | Check for secure connection enforcement, admin URL exposure, missing CSP/HSTS headers, and proper cache rules for sensitive data. |
| 📊 Technical SEO Review | Scan for proper title/meta tags, H1 hierarchy, canonical setup, indexability issues, and presence of structured data where applicable. |
| ♿ Accessibility Snapshot | Detect contrast issues, missing labels, broken ARIA attributes, and tab/focus problems to improve accessibility and compliance. |
