WooCommerce sites get slow when hosting resources are limited, pages run heavy scripts, or the database is bloated. Common causes include having too many plugins, poorly coded themes, oversized images, excessive product variations, and slow third-party requests (such as fonts, ads, and analytics). Caching misconfiguration, missing object cache, and the absence of a CDN also hinder performance. High admin-ajax or REST requests, scheduled actions backlog, and large autoloaded options can overload PHP and MySQL. Checkout can slow due to payment gateway calls or shipping rate APIs. Finally, malware, hotlinked media, and uncached cart fragments can keep pages dynamic and slow. Run a speed test and check server logs.
