# 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`
|
||
```javascript
|
||
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
|
||

||
## 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**
|
||
