This guide provides suggestions for improving the response time of your Web Hosting with Infomaniak.

Preamble

• TTFB, or *Time To First Byte*, is a unit of measurement used to evaluate the response speed of a web server.
• TTFB measures the time between an HTTP request from a user or browser and the receipt of the first byte of the page to be viewed.
• This delay is particularly important. It can be part of the SEO criteria considered by search engines like Google.
• Make your life easier! If needed, local partners recommended by Infomaniak can handle these procedures. Launch a free call for tenders. They handle everything, freeing you from technical details.

Suggestions for improving TTFB

To speed up the site and achieve a better TTFB value:

• Use a content delivery network (CDN).
• Optimize the site's code.
• Optimize database queries.
• Limit HTTP requests.
• Embed CSS and JavaScript in your HTML pages to avoid calling external resources.
• Use an RFPL (*Response First, Process Later*) caching system.

Refer to the article by Criticalcase (in English) for more information.

Test the server response speed

If you are unsure about the server response speed, you can create a file called index2.html that will be saved at the same level as the index.html (or .php) file, and thus perform an optimization test (e.g., domain.xyz/index2.html) without the main site/CMS being taken into account.

If the response time is normal, this means that the slowness comes from the site and not the server.
