Slow part of website

Hi everyone, I have a speed issue on one of our sites:

As you see, everything loads pretty ok, but the slieder (Flexslider), is delayed by about 4 seconds.

Can someone help me to shed a light on this, please?

All help appreciated,

It’s because you’re waiting until the entire page has finished loading.

The documentation page says:
“The $(window).load() is required to ensure the content of the page is loaded before the plugin initializes.”

Solution #1: Use images with a smaller filesize
Solution #2: Use a different slider
