Quick overview:
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 16 blocking script resources and 14 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 images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 273.3KiB (36% reduction).
Compressing https://www.tdisdi.com/wp-content/uploads/2018/07/ladder-sdi.jpg could save 74.7KiB (29% reduction).

Leverage browser caching for the following cacheable resources:

...
Reduce server response time
In our test, your server responded in 1.4 seconds.
There are many factors that can slow down your server response time. Please read our recommendations to learn how you can monitor and measure where your server is spending the most time.
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.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 43% of the final above-the-fold content could be rendered with the full HTML response.
...
Minify JavaScript
Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 47.6KiB (33% reduction).
Minifying https://code.jquery.com/ui/1.11.4/jquery-ui.js?ver=c48b56ca4f3b439a65fae91e48346e1c could save 40.1KiB (36% reduction) after compression.
...
Minify CSS
Compacting CSS code can save many bytes of data and speed up download and parse times.
Minify CSS for the following resources to reduce their size by 1.6KiB (17% reduction).
Minifying https://code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css?ver=c48b56ca4f3b439a65fae91e48346e1c could save 1.3KiB (17% reduction) after compression.
