# Fast WordPress for Online Course Creators — xSpeed Cache > Launch-day rushes, logged-in students, and video lessons: how course creators keep WordPress LMS sites fast with xSpeed Cache — with the exact AI prompt. Page: https://xspeedcache.com/use-cases/for/course-creators/ Category: Learning & community Also covers: course, elearning, lms, learndash, tutor, training, academy, school, university, college, coaching, bootcamp, certification, driving school, music lessons ## The speed brief - **Who arrives** — A student who paid, mid-lesson, expecting it to work - **What they want** — The lesson, the progress bar, the next module - **How long you get** — None. They already bought — now it just has to be good. ## When speed decides the outcome 1. **The launch** — Everyone enrols in the same 48 hours, and the server finds out live. 2. **The lesson** — Logged-in pages skip most caches, so students get the slow version. 3. **The refund** — A course that feels broken gets refunded, however good the content is. ## The story When Elena opens enrolment twice a year, two things spike at once: the public sales page (thousands of visitors from her launch emails) and the student area (every new student logging in to start lesson one the same evening). They are opposite problems. The sales page is identical for everyone — pure caching. The lesson pages are personal — progress bars, completions, access checks — and can’t be page-cached at all. Her old setup treated both the same way and failed at both. Split correctly — sales pages prewarmed static, student area on Redis with REST caching — both spikes now land softly. Launch day is loud in Slack and quiet in the error logs. ## What a site like this needs - **A sales page that absorbs the launch list** — Thousands of identical page views in an hour: prewarmed static HTML. - **Fast lessons for logged-in students** — Progress and access checks served from memory, not the database. - **Video without the drag** — Lesson embeds load on demand, not all at once. ## The xSpeed features doing the work - **Page cache + prewarming** — Sales and curriculum pages stay permanently warm for launch traffic. Guide: https://xspeedcache.com/docs/scheduled-cache-prewarming - **Redis object cache** — Access checks and progress queries served from memory for every logged-in student. Guide: https://xspeedcache.com/docs/object-cache-redis-memcached - **REST API cache** — The LMS plugin’s own data traffic stops hammering the database. Guide: https://xspeedcache.com/docs/rest-api-cache ## The exact AI prompt Connect via xSpeed MCP (https://xspeedcache.com/docs/mcp-server-setup) or xSpeed Hub, then paste: ``` My course launch opens Tuesday. Using xSpeed, prewarm the sales and curriculum pages, exclude everything behind login from the page cache, connect Redis for the student area, enable REST API caching, and set heartbeat control so idle dashboards don’t drain the server. Show me queries-per-page for a lesson page before and after. ``` What happens: The launch list hits static pages; the new students hit a memory-backed classroom. Both feel instant. ## FAQ ### Why is my course site fast for visitors but slow for students? Because page caching only covers logged-out pages. Students need the object cache: with Redis or Memcached, the repeated access and progress queries that make lessons slow come from memory instead — typically cutting database work per page by an order of magnitude. ### Can students ever see each other’s progress via caching? No. Personalised pages are excluded from the page cache by login cookie; the object cache stores query results, never rendered personal pages. Each student’s view is always their own. ## More - [Full playbook: xSpeed for Membership & LMS](https://xspeedcache.com/use-cases/membership-lms/index.md) - [Learning & community: Nonprofits & churches](https://xspeedcache.com/use-cases/for/nonprofits/index.md) - [Learning & community: Communities & forums](https://xspeedcache.com/use-cases/for/communities/index.md) - [Learning & community: Schools & universities](https://xspeedcache.com/use-cases/for/schools/index.md) - [All use cases](https://xspeedcache.com/use-cases/index.md) - [Free plugin](https://wordpress.org/plugins/xspeed/)
