Quick overview:
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 3 blocking script resources and 15 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Optimize CSS Delivery of the following:

...
Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
https://www.google-analytics.com/gtm/js?id=GTM-PXBHX6T&t=gtm3&cid=1136090433.1575837347 (15 minutes)
...
Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
71.3KiB of the HTML response was required to render the above-the-fold content. This requires 3 network round-trips. However, if the HTML response were compressed, then the HTML required to render the above-the-fold content could be delivered in just 1 network round-trips. Enable compression for the HTML response in order to prioritize the visible content for this page.
Only about 24% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.
...
Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 67.3KiB (84% reduction).
Compressing https://www.ru.nl/ could save 67.3KiB (84% reduction).
Minify HTML
Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.
Minify HTML for the following resources to reduce their size by 18.6KiB (24% reduction).
Minifying https://www.ru.nl/ could save 18.6KiB (24% reduction).
