Install PageSpeed Tools

To enable Google PageSpeed Tools:

1. Open the Manager (manager.infomaniak.com)
2. Go to Web Hosting
3. Click on the relevant hosting/domain name
4. Under Sites, click on the domain name of the relevant site
5. Click on Advanced settings
6. Click on the Apache tab
7. Enable the option Google Page Speed optimisation

Default setting

A caching system is also in place for the site files. This is updated every 15 minutes.

If necessary, it’s possible to customise certain directives via the website’s .htaccess file: https://modpagespeed.com/doc/configuration#htaccess

But beware: according to this Google thread and this discussion, unfortunately mod_pagespeed doesn’t take into account the directives in a ".htaccess" file when accessing a dynamic file. To avoid / get rid of mod_pagespeed, it must be disabled from the Manager.

Known incompatibilities

• ownCloud
• WP Rocket

In addition, it’s not unusual for warnings to appear after installing PageSpeed:

"By default, mod_pagespeed will fetch css/js/images using http. If the webserver doesn’t respond within 50ms (by default), it will abort the request, and log the timeout messages you’re seeing...”

In a shared environment, it’s not a concern or an anomaly to slightly exceed the 50ms response time.
