Web Performance

Communication Protocols You Should Know: HTTP/2, gRPC, QUIC Three main protocols shape how data travels on the web today: HTTP/2, gRPC, and QUIC. They are designed to speed up connections, reduce delays, and make communication more reliable. Understanding them helps you pick the right tool for the job and avoid common bottlenecks. HTTP/2 fixes many issues of HTTP/1.1. It allows multiplexing, so many requests share a single TCP connection without waiting for earlier responses. It also uses header compression to save bandwidth. Because HTTP/2 runs over TCP, it gains reliability, but head‑of‑line blocking can still slow some flows if a single stream stalls. ...

Caching Strategies to Speed Up Web Apps Caching is a simple idea with big results. When you store copies of responses, users get faster pages and your servers handle fewer repeated requests. The trick is to cache wisely: different layers, different data, and clear rules for when to refresh. Caching works best when you balance freshness and speed. Static assets like images and scripts can live longer in caches, while frequently changing data needs shorter lifetimes or smart revalidation. The goal is to serve correct content without repeating heavy work on every request. ...

Web Development Trends for the Next Decade The next decade will reshape how we build and run websites. The pace of change is fast, but some patterns stay useful: performance, accessibility, and security. This article highlights trends that matter for teams and creators who want reliable, lasting results. AI-assisted tools will become common in everyday work. Expect smarter coding assistants, faster testing, and better accessibility checks. These aids help with boilerplate, code reviews, and catching issues before they reach production. The goal is to save time while keeping design and user needs clear. ...

Content Delivery Networks: Speeding Up the Web A Content Delivery Network, or CDN, places copies of your site’s files on servers around the world. This setup brings data closer to visitors, so pages load faster even when someone is far from your origin host. For many sites, a CDN is a simple and effective way to improve user experience. How it works: when a user requests a page, the CDN selects the nearest edge server. If the content is cached there, the edge serves the file quickly. If not, it fetches it from your origin, stores a copy at the edge, and serves it to the user. Over time, popular files stay handy at nearby locations, so future requests travel shorter distances and load more quickly. ...

Content Delivery Networks: Speeding Up Global Websites Content Delivery Networks (CDNs) place copies of your site’s static files on servers around the world. When a user visits, the CDN serves content from the nearest edge server. This reduces distance, lowers latency, and helps pages load quickly. How it works: An edge network caches images, scripts, styles, and other assets. If a file is cached and fresh, the edge serves it directly. If not, the edge fetches it from your origin, stores a copy, and serves it to the user. The whole process happens in milliseconds. ...

Content Delivery Networks: Speeding Up Global Sites Content Delivery Networks (CDNs) place copies of your files on servers around the world. When a user visits your site, the CDN chooses the nearest edge server to send images, scripts, and videos. This reduces distance data travels and lowers latency, so pages load faster. CDNs primarily cache static assets like images, CSS, and JavaScript. They can also optimize delivery for video streams and adapt to different devices. A CDN works with your origin server: it fetches content when needed and stores it for future requests. You control how long content stays at the edge with cache rules and TTL values. ...

Content delivery networks and global performance A content delivery network (CDN) places copies of your files on servers around the world. When a user requests a page, the CDN serves assets from the edge location closest to that user. This shortens travel distance, reduces round trips, and helps pages load faster. The result is better experiences for visitors, regardless of their location or device. CDNs are useful for blogs, storefronts, and apps alike. ...

Content Delivery Networks: Speeding Up the Internet Content Delivery Networks, or CDNs, speed up the web by storing copies of your site’s files on servers around the world. When a user opens a page, the CDN tries to serve images, scripts, and pages from the nearest edge server. This shortens travel distance, lowers latency, and makes pages feel faster even for visitors far away. How it works: edge servers cache static files like images, CSS, and JavaScript. If the file is in cache and fresh, it is sent directly. If not, the edge fetches it from your origin server, forwards it to the user, and saves a copy for the next request. Many CDNs also handle dynamic content by smart routing and light processing at the edge, so personalized data can travel quickly while keeping security high. ...

Reducing Latency with CDN and Edge Compute Latency is more than a number. It shapes how users feel about your site. A fast experience boosts engagement and trust. Two complementary tools help: a content delivery network (CDN) and edge compute. Together, they move content closer to visitors and cut back on trips to the origin server. How a CDN helps A CDN stores copies of static assets—images, styles, scripts—in many locations around the world. When someone asks for a file, the edge server nearest them serves it. This reduces travel distance and speeds up loading times. ...

Content Delivery Networks: Speeding Up Global Websites Content Delivery Networks (CDNs) are groups of servers spread around the world. When a user visits your site, the CDN tries to serve most files from a nearby edge location instead of reaching back to your origin every time. If the file is already cached on that edge, it travels a short distance and loads quickly. If not, the edge fetches it from your origin and stores a copy for next requests. This simple approach cuts network hops, lowers bandwidth from the origin, and helps pages stay fast even during traffic surges. ...
