Frequently Asked Questions
Website Performance FAQs
Quick answers to the questions readers ask most often about website performance.
What are Core Web Vitals?
Google's set of user-experience metrics: Largest Contentful Paint (LCP) for loading, Interaction to Next Paint (INP) for responsiveness, and Cumulative Layout Shift (CLS) for visual stability.
What is a good page-load time?
Aim for LCP under 2.5 seconds, INP under 200 milliseconds, and CLS below 0.1 on both mobile and desktop.
How does hosting affect site speed?
Server response time (TTFB), storage type (NVMe vs SATA), PHP version, and physical distance to visitors all influence how quickly a page starts rendering.
Should I use a CDN?
Yes for any site with a global audience. A CDN caches static assets near users and reduces origin load. Cloudflare, BunnyCDN, and Hostinger's built-in CDN are popular choices.
How can I optimize images?
Serve modern formats (WebP, AVIF), size images to the largest render dimension, add width/height attributes to prevent layout shift, and lazy-load below-the-fold images.
What causes high TTFB?
Slow database queries, uncached dynamic pages, distant server locations, or a shared host under load. Enable full-page caching or upgrade to a faster plan.
