Black Friday falls on 27 November 2026. A virtual waiting room lets visitors in, in an orderly sequence and at the pace of the shop. Where it sits technically, which status codes it sends and why robots.txt and the payment return never belong in the queue.
A font is embedded, not ordered – and that is exactly where the trouble starts. License scope, place of delivery and load order decide both the legal and the performance side.
A lab run measures one page under fixed conditions, while field data collects what really reaches visitors. How the two belong together, why the 75th percentile decides and how to build your own collection without a third-party service.
Slow shops rarely have a visible problem, they have an expensive one. How the slow query log, measured execution plans and matching indexes reveal where the compute time actually goes.
Peak season is in the calendar, yet hardly anyone knows their shop's capacity ceiling. This guide shows how to derive a load profile from last year's data, run a staged load test against a production-like copy, define target value, warning threshold and emergency stop, and build an emergency plan with rehearsed relief valves – including an operating calendar from July to January.
In PHP 8.5 OPcache is built in. This guide shows which OPcache values save response time in a shop, when JIT tracing helps on CPU-bound routes and hurts on I/O-bound ones – including migration from PHP 8.4.
Chat, ads and tracking load more JavaScript than your own shop code at the median. How to find, defer, replace and remove third-party scripts without losing features – and win back load time.
Late order mails, a stale search index, an outdated sitemap: how to move the Shopware message queue into production with CLI workers, separate queues and alerting.
The storefront HTTP cache now works with login and a filled cart. How the sw-cache-hash works, what changes in invalidation and how to prepare extensions safely.
Larger targets, terms explained, input help, clear focus, no time limits

Our anonymous reach measurement runs without cookies and without IP storage, including campaign parameters in links – we do not ask for consent for it because none is legally required.
Strictly required: language preference, core site functions and storing your cookie choice. Without these the site does not work. Settings you choose yourself (light/dark appearance, accessibility) are kept in your browser's local storage only once you choose them; "Reset" in the accessibility settings removes them.
Records your interactions (clicks, scrolling, inputs) pseudonymously so we can spot usability issues. Form field inputs are masked automatically before storage; your IP address is not saved with the recording. Served from our own domain, no external tool. Opt-in, revocable any time.
