# How to Fix High Server Response Times (TTFB)

# Guide to Improving TTFB with WP Compress

Follow these steps to reduce your TTFB:

1. **Activate the Recommended Mode in WP Compress**

   Start with the recommended settings in WP Compress. This should solve most issues instantly.
   `WP Compress > Settings > General > Optimization Mode > Recommended`

2. **Ensure Advanced Caching is ON**

   Make sure that advanced caching is activated. If not, turn it on.
   `WP Compress > Settings > CDN > Advanced Caching > ON`

3. **Check your `/` Directory Size**

   If the problem persists, check the size of your root (`/`) directory. If it's significantly large (for example, over 700KB), proceed to the next steps.

4. **Turn ON Critical CSS**

   Enabling Critical CSS will extract and inline the CSS needed for rendering the above-the-fold content. It helps in rendering the webpage faster.
   `WP Compress > Settings > CSS > Critical CSS > ON`

5. **Turn OFF Inline CSS**

   In case your directory size is large, disabling Inline CSS can help as it reduces the overall size of the page.
   `WP Compress > Settings > CSS > Inline CSS > OFF`

## Additional Suggestions:

- **Minimize Redirects**

  Excessive redirects can lead to slower TTFB. Try to minimize the number of redirects on your website.

- **Keep Your WordPress Updated**

  Regularly updating your WordPress installation, themes, and plugins can help improve overall performance, including TTFB.

- **Use a Content Delivery Network (CDN)**

  If not already in use, our CDN can help to significantly reduce TTFB by serving your website's static files from a server location closer to the visitor.

Remember, TTFB can also be affected by factors outside your website, such as network latency and server performance. Hence, it is also essential to choose a good hosting provider.
