Website Performance Analysis

Executive Summary

Your website has several critical performance issues that need to be addressed. The current setup prioritizes development convenience over user experience, resulting in slower load times, higher bandwidth usage, and poor Core Web Vitals scores.

Overall Performance Grade: C- (Needs Improvement)

---

Critical Issues (High Priority)

1. Image Optimization Disabled ⚠️ CRITICAL

Location: next.config.mjs:7

images: {
  unoptimized: true,  // ❌ This disables Next.js image optimization
}

Impact:

• Images are served at full resolution without compression
• No automatic WebP/AVIF format conversion
• No responsive image sizing
• Significantly larger page sizes (often 2-5x larger than needed)
• Slower page loads, especially on mobile

Recommendation: Remove unoptimized: true and enable Next.js image optimization

---

2. Excessive Client-Side Data Fetching ⚠️ CRITICAL

Affected Components:

• navbar.tsx - Fetches logo on client
• main-hero.tsx - Fetches content on client
• hero-section.tsx - Fetches content on client
• testimonials.tsx - Fetches testimonials on client
• trusted-by.tsx - Fetches logos on client
• footer.tsx - Fetches logo and social icons on client

Impact:

• 6+ separate API calls on every page load
• No server-side rendering benefits
• Slower Time to First Contentful Paint (FCP)
• Poor Largest Contentful Paint (LCP) scores
• Content flashes/flickers as data loads
• Higher server load

Recommendation: Move data fetching to server components or use Next.js API routes with proper caching

---

3. Using Regular <img> Tags Instead of Next.js <Image> ⚠️ HIGH

Locations:

• navbar.tsx:79 - Logo image
• testimonials.tsx:183 - Avatar images
• trusted-by.tsx:147 - Logo images

Impact:

• No automatic lazy loading
• No responsive image sizing
• No blur placeholder support
• Missing performance optimizations

Recommendation: Replace all <img> tags with Next.js <Image> component

---

4. No Lazy Loading for Below-the-Fold Content ⚠️ HIGH

Impact:

• All components load immediately, even if not visible
• Unnecessary JavaScript execution
• Slower initial page load

Recommendation: Implement dynamic imports with next/dynamic for below-the-fold components

---

5. Heavy Animation Library (Framer Motion) ⚠️ MEDIUM

Location: Multiple components using framer-motion

Impact:

• Large JavaScript bundle (~50-70KB gzipped)
• Animation code executes on every page load
• Can cause layout shifts

Recommendation:

• Consider lighter alternatives for simple animations
• Or lazy load animation components
• Use CSS animations where possible

---

Moderate Issues

6. No API Response Caching Strategy

Impact:

• Every page load makes fresh API calls
• Higher server load
• Slower response times

Recommendation: Implement proper caching headers and Next.js revalidate options

---

7. Multiple API Calls Could Be Combined

Impact:

• Network overhead from multiple requests
• Slower overall data loading

Recommendation: Create a single API endpoint that returns all page data, or use parallel fetching with proper caching

---

8. No Error Boundaries

Impact:

• If one component fails, entire page can crash
• Poor user experience

Recommendation: Add React error boundaries

---

Performance Metrics (Estimated)

Based on current implementation:

Metric	Current	Target	Status
First Contentful Paint (FCP)	~2.5-3.5s	<1.8s	❌ Poor
Largest Contentful Paint (LCP)	~4-6s	<2.5s	❌ Poor
Time to Interactive (TTI)	~5-7s	<3.8s	❌ Poor
Total Blocking Time (TBT)	~800-1200ms	<200ms	❌ Poor
Cumulative Layout Shift (CLS)	~0.1-0.2	<0.1	⚠️ Needs Work
Bundle Size	~500-700KB	<300KB	❌ Large

Recommended Improvements (Priority Order)

Phase 1: Critical Fixes (Immediate Impact)

1. Enable Image Optimization

   • Remove unoptimized: true from next.config.mjs
   • Replace all <img> tags with Next.js <Image>
   • Add proper width, height, and alt attributes
   • Use priority prop for above-the-fold images only

2. Convert to Server Components

   • Move data fetching to server components
   • Use async/await in server components
   • Keep client components only for interactivity

3. Implement Lazy Loading

   • Use next/dynamic for below-the-fold components
   • Add loading="lazy" for images below the fold

Phase 2: Optimization (High Impact)

4. Optimize API Calls

   • Combine multiple API calls where possible
   • Implement proper caching with revalidate
   • Use Next.js API routes for data aggregation

5. Reduce JavaScript Bundle

   • Code split heavy dependencies
   • Lazy load Framer Motion
   • Tree-shake unused code

6. Add Loading States

   • Implement proper loading skeletons
   • Prevent layout shifts during data loading

Phase 3: Advanced Optimizations

7. Implement ISR (Incremental Static Regeneration)

   • Pre-render pages at build time
   • Revalidate in background

8. Add Service Worker / PWA

   • Cache static assets
   • Offline support

9. Optimize Fonts

   • Use next/font for font optimization
   • Preload critical fonts

Quick Wins (Can Implement Today)

1. ✅ Enable image optimization (5 min)
2. ✅ Replace <img> with <Image> (30 min)
3. ✅ Add loading="lazy" to below-the-fold images (10 min)
4. ✅ Add priority to hero images (5 min)
5. ✅ Implement dynamic imports for below-the-fold components (30 min)

Estimated Time: ~1.5 hours Expected Improvement: 30-40% faster page loads

Testing Recommendations

After implementing fixes, test with:

• Lighthouse (Chrome DevTools)
• PageSpeed Insights (Google)
• WebPageTest
• Next.js Analytics (already installed)

Target scores:

• Performance: 90+
