# Speed up WordPress with the page cache on Linux hosting

> Turn on the built-in WordPress page cache on HyperDC Linux hosting, check that pages come from the cache and purge it; saving a post refreshes its pages.

Difficulty: Beginner

Most visitors of a WordPress site see the same pages. The page cache keeps those finished pages and hands them out without running WordPress again, so pages load faster and the site holds more visitors at once.

## How the page cache works

The page cache works in front of WordPress.

- Visitors who are not signed in get kept pages straight from the cache.
- Signed-in visitors, carts, checkout and account pages always reach WordPress.
- Publishing or changing content clears the pages it touches, such as the post, its archives and the home page, and the next visitor gets the new version.

## Step 1: Turn on the page cache

1. Open **Performance** on your service page and choose the site.
2. Under **WordPress optimizer**, open **Tuning**.
3. Next to **Page cache**, select **Switch On** and confirm.

## Step 2: Check that it works

Visit your home page once in a private browser window, then select **Check Again** in **Performance**. Under **Home page speed**, **First byte from the page cache** shows **Hit** when the page came from the cache.

**Verify:** the second visit shows **Hit**, and the page loads noticeably faster.

## Clear the cache

After a big change, such as a new theme or menu, select **Purge** next to **Page cache** and confirm. Every kept page is removed; the next visitors wait for WordPress once, and their pages are kept again.

To stop using the cache, select **Switch Off**. Every visit runs WordPress again.

## Troubleshooting

**The check keeps showing Miss.** A plugin that gives every visitor a cookie, or a page that asks not to be kept, keeps it out of the cache. **Recommendations** in the same tab names what it found.

**A change does not show.** Select **Purge**, then reload the page.

## Frequently asked questions

### Do I need a cache plugin?

No. The page cache is part of the hosting and works in front of WordPress. Switching it on adds a small plugin of ours to WordPress, which tells the cache what to clear when your content changes.

### Do my visitors see old pages after I edit a post?

No. Publishing or changing content clears the pages it touches, and the next visitor gets the new version.

### Are carts and signed-in pages cached?

No. Signed-in visitors, carts, checkout and account pages always reach WordPress.

### Should I keep another page cache plugin?

No. Two page caches on top of each other only get in each other's way. Deactivate the other one's page cache and keep its other optimisations if you like.
