Low Latency Design & Performance Optimization
Architect systems that respond in milliseconds. Expert optimization for caching, CDN, databases, and real-time applications.
Slow Applications Cost You Users and Revenue
Every 100ms of latency costs 1% conversion. Users expect instant responses.
⏱️ Slow Page Loads
53% of mobile users abandon sites taking >3 seconds. Every second of delay = 7% fewer conversions.
🗄️ Database Bottlenecks
Unoptimized queries, missing indexes, and N+1 problems kill performance at scale.
🌍 Global Latency
Users across continents experience 300-500ms delays from server distance alone.

Frequently Asked Questions
How fast is "fast enough"?
Target <100ms for API responses, <1s for page loads, <2.5s for Largest Contentful Paint (LCP). These are Core Web Vitals thresholds that impact SEO and user experience.
Where should I start with optimization?
Start with easy wins: CDN for static assets, database query optimization, API response caching. These deliver 60-70% of potential gains with minimal risk. Advanced optimizations (edge computing, custom protocols) come later.
How much does CDN cost?
Cloudflare: Free tier available, Pro at £16/month. AWS CloudFront: £0.068/GB (decreases with volume). For most sites, CDN costs <£80/month while dramatically improving performance globally.
Will caching cause stale data issues?
Properly implemented caching with smart invalidation prevents stale data. We use cache-control headers, versioned URLs, and event-driven invalidation to ensure users always see fresh content when needed.
