Performance Architecture
Multi-Tier Caching & Edge Delivery
How Dev Pattern Labs engineers sub-second Core Web Vitals, 95+ PageSpeed scores, and zero-downtime scalability using intelligent edge, server, and browser caching.
The 5 Tiers of Caching
A Complete Defense Against Latency
Speed is not an afterthought — it is built into every layer of our software architecture from DNS to the client browser.
Global Edge CDN Caching
Static HTML and pre-rendered pages are deployed across 300+ edge Points of Presence (PoPs) globally. Incoming requests are answered at the closest server to the user, driving TTFB (Time to First Byte) under 50 milliseconds.
Next.js 15 Incremental Static Regeneration (ISR)
We configure route-level revalidation (`export const revalidate = 60`) on data-driven routes. Content updates in the background without user delays, delivering the speed of static HTML with the freshness of a live database.
In-Memory Redis Object Caching
For dynamic e-commerce stores (WooCommerce) and relational databases, repeated SQL queries are cached in high-speed Redis RAM. Complex queries return in microseconds, preventing server CPU spikes during flash sales.
Immutable Browser Cache-Control Headers
All compiled scripts, WebP/AVIF images, and fonts are fingerprinted with SHA hashes and served with `Cache-Control: public, max-age=31536000, immutable`. Repeat visitors download zero redundant assets.
Service Worker & Offline PWA Caching
For operational SaaS like PostSprint and our DPLS Milk collection app, Service Workers intercept requests and manage offline cache stores, enabling instantaneous interaction even in low-connectivity rural environments.
