Docker Performance Optimization: Real-World Strategies

DZone

After optimizing containerized applications processing petabytes of data in fintech environments, I've learned that Docker performance isn't just about speed it's about reliability, resource efficiency, and cost optimization. Let's dive into strategies that actually work in production. We can fix that with this code below:

Site-Speed Topography

CSS Wizardry

When first working on a new site-speed engagement, you need to work out quickly where the slowdowns, blindspots, and inefficiencies lie. I want to be able to form hypotheses and draw conclusions without viewing a single URL or a line of source code. Now, let’s move on to gaps between First Contentful Paint and Speed Index.

Why vulnerability management enhances your cloud application security strategy

Dynatrace

Meeting the need for speed without exposing exploitable vulnerabilities requires that teams adopt DevSecOps approaches that “shift right” (observability in production) as well as “shift left” (observability in development). Static code scanners don’t cover all scenarios in production, and vulnerabilities often leak through to production.

The Three Cs: Concatenate, Compress, Cache

CSS Wizardry

Given that 66% of all websites (and 77% of all requests ) are running HTTP/2, I will not discuss concatenation strategies for HTTP/1.1 We need to learn a little bit more about the rest of our setup before we can make a final decision about our concatenation strategy. ?️ What happens when we adjust our compression strategy?
