How can I improve the speed of an e-commerce website?

Question

I manage an e-commerce website that contains many product images and category pages. I want to improve its loading speed, server response time, image delivery, and Core Web Vitals. Could you please suggest the best caching, CDN, image optimization, and server configuration methods for an e-commerce website? I would also appreciate recommendations for reducing page load time without affecting image quality or website functionality.

Hi there, For an image-heavy e-commerce site, the biggest wins usually come in this order. Offload images to DigitalOcean Spaces with the built in CDN. Upload your product images there and serve them from the CDN edge rather than your origin server. This alone can cut page load times significantly for visitors far from your server’s region, and Spaces pricing is flat and predictable: https://docs.digitalocean.com/products/spaces/ Optimize images before uploading. Convert to WebP format which is smaller than JPEG and PNG with no visible quality loss. Tools like sharp in Node.js handle batch conversion well. Set explicit width and height attributes on image tags to avoid layout shift which hurts Core Web Vitals. For database performance, DigitalOcean Managed PostgreSQL or MySQL includes connection pooling via PgBouncer built in, which reduces connection overhead under traffic spikes. Enable slow query logging and fix the worst offenders before scaling up: https://docs.digitalocean.com/products/databases/ Add full page caching at the server level. Nginx FastCGI cache or a plugin like WP Rocket serving static HTML to anonymous visitors means your server skips PHP and the database entirely for most product page views. For Redis object caching, DigitalOcean Managed Redis is worth using instead of running Redis yourself on the same Droplet. Keeps your app server resources free for handling requests: https://docs.digitalocean.com/products/databases/redis/ Put Cloudflare in front for an extra CDN and caching layer. The free tier gives you DDoS protection and automatic WebP conversion with Polish enabled. For Core Web Vitals, Largest Contentful Paint is almost always the main issue on product pages and is usually the hero image loading slowly. Fixing image delivery through Spaces CDN fixes the score.

Hi there, On the Spaces CDN, the default Edge Cache TTL is one hour, and you can raise it for product images since those rarely change, which gets you longer edge retention without extra configuration. One caveat that catches people out: presigned URLs are not cached by the Spaces CDN, so if your product images are served through signed, access-restricted URLs rather than public ones, you will not see the CDN performance benefit at all. Worth checking that your images are public-read if speed is the priority. If you want your own domain on the CDN endpoint instead of the default ..cdn.digitaloceanspaces.com, DigitalOcean supports a custom subdomain with either a Let’s Encrypt certificate (if your DNS is on DigitalOcean) or your own certificate otherwise. DigitalOcean’s managed databases support up to two read-only replica nodes per cluster, which you can point catalog and search queries at to take that load off the primary, keeping the primary free for checkout and order writes. These are managed through the control panel, doctl databases replica, or the API, and a replica can later be promoted to its own independent cluster if needed. Regards
