How do you optimize the performance of a Shopware shop?
Shopware CE comes with its own set of performance levers that differ from a classic website. The central ones are: the Elasticsearch configuration for fast product and faceted search, HTTP cache warming so that frequently accessed category and product pages are already in the cache, lean Twig templates for short render times, and a correctly tuned Varnish reverse proxy that serves finished pages straight from memory.
On top of that come shop-typical topics such as the number of plugins, the generation of image variants (thumbnails) and database performance with large catalogs containing many variants. Especially during load spikes, for instance at a campaign launch, the caching strategy decides availability and conversion. Our dedicated Shopware performance page covers these topics in detail, and for shops with high order volumes our e-commerce solutions are worth a look.
