Delayed opening issue of slider

[foz]

Hello everyone, on the homepage of my site, which is built with Wordpress, there is a slider made with revolution slider. However, the slider opens about 5-6 seconds after the site is opened. Everything else on the homepage loads instantly, except for the slider which loads late. How can I come up with a solution for this? I clear the cache three times a day. Website: zorlunakliyat.com
