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.

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.

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.
