Drupal 8 enables caching by default for anonymous visitors. That is sufficient for small to medium-sized websites with moderate traffic. You can turn it off for development purposes by setting it to “”. Be sure to turn it back on before you launch or your site will be slow.
- Go to the Performance admin page by clicking Manage > Configuration > Development > Performance (Coffee: “performance”) or visit http://yourDrupal8site.dev/admin/config/development/performance in your browser.
- You need to make a judgment call on Page caching maximum age. How quickly does your website content change? Every fifteen minutes? Every hour? Daily?
- 1 day—for websites that are only updated a couple of times per week. There is no commenting or other interaction on the site. (e.g. lead generation brochure site)
- 1 hour—for websites that are updated once or twice per day. (e.g. eCommerce)
- 15 minutes—for frequently updated websites. (e.g. news sites) 3. Under “Bandwidth Optimization”, make sure “Aggregate CSS files” and “Aggregate JavaScript files” are both selected.
- Click the Save configuration button. 5. If you use Views or Panels, you can get more fine-grained in your cache settings. The caching on each block can be customized as well.
