How We Helped a Hyderabad SaaS Reduce Load Time from 8s to 0.9s
Case study: Migrating a Hyderabad-based B2B SaaS from WordPress to Next.js, reducing load time from 8 seconds to under 1 second.
Background
A Hyderabad-based B2B SaaS platform approached ENFLENZ with a problem: their WordPress website was loading in 8 seconds. PageSpeed score: 32.
Users were bouncing. Trial signups were flat. Their Google Ads cost-per-click was rising because Google's Quality Score penalized their slow landing pages.
The Audit
Our technical audit found 127 issues:
| Category | Issues Found | Impact |
|---|---|---|
| Hosting | Shared PHP/Apache hosting, no CDN | 3-5s server response time |
| Plugins | 23 active plugins, several conflicting | 1.2s overhead, 8 security warnings |
| Images | 47 unoptimized images, no lazy loading | 2.3s loading time |
| Code | Render-blocking JS/CSS in head | 1.1s delay to first paint |
| Caching | No page caching, no Redis | 1.5s database queries |
The Migration Strategy
We didn't just rebuild — we re-architected:
1. Tech Stack Change
- WordPress → Next.js 16 (App Router)
- PHP/MySQL → PostgreSQL
- Shared hosting → Vercel Edge Network
2. Performance Budgets
- LCP: < 1.0s
- FID: < 100ms
- CLS: < 0.1
- Bundle size: < 500KB
3. Asset Optimization
- Images converted to WebP, lazy-loaded
- CSS purged to 12KB (was 284KB)
- Fonts self-hosted with
font-display: swap
Implementation Timeline
| Week | Activities |
|---|---|
| Week 1 | Audit, architecture design, component planning |
| Week 2 | Next.js scaffold, API routes, database migration |
| Week 3 | Component development, page builds, testing |
| Week 4 | Performance tuning, A/B testing setup, launch |
Results (After 30 Days)
| Metric | Before | After | Improvement |
|---|---|---|---|
| PageSpeed Score (Desktop) | 32 | 97 | +203% |
| PageSpeed Score (Mobile) | 28 | 95 | +239% |
| Load Time (LCP) | 8.2s | 0.9s | -89% |
| Bounce Rate | 68% | 42% | -26% |
| Trial Conversion | 2.1% | 4.2% | +2.8x |
| Google Ads CPC | ₹45 | ₹22 | -51% |
| Monthly Organic Traffic | 1,200 → 3,600 | 3x |
Key Takeaways
- Performance = Revenue — Every 0.1s improvement in LCP increased conversion by 3.2%
- WordPress plugins are technical debt — Each plugin adds 20-80ms of unavoidable overhead
- Edge deployment matters — Serving from Singapore instead of Mumbai reduced TTFB from 420ms to 28ms
- Caching isn't enough — You need a fundamentally different architecture
Lessons Learned
The hardest part wasn't the technical migration — it was helping the client understand that their content strategy needed to change too. WordPress's "add a plugin for everything" mentality had created 23 different content types, many redundant. We consolidated into 5 clean content models.
Cost
The full migration cost: ₹1,25,000 (delivered in 4 weeks).
For comparison: rebuilding the same site from scratch on WordPress would have cost ~₹2,00,000 with ongoing maintenance of ₹15,000/month. The Next.js version has near-zero maintenance costs.
