Revolution slider on homepage takes 3 minutes or more to load on mobile and pc (tested on Internet Explorer, Firefox and Chrome). It consists of two slides with low res images (72 ppi).
Is there a way to accelerate load times (no caching involved)?
You can adjust Slider Settings from Revolution Slider. They’ve also caching system on every slide. Play around on this.
I think you’ve enabled Slider Preloader that’s why you’re seeing it’s loading, actually it’s loading all images. I think there’s no problem with this.
