I Buyed it yesterday, and It wasnt help my web site, the updated that you allow to buy it wasnt needed... my web now it is slower and didnt fix the problem of charging. It is the same that before I updated, or even worst.
Thank you for getting in touch with us. My name is Attila and I'm happy to assist you today. I appreciate your patience while we've been working towards your ticket.
LayerSlider is well optimized, it does not slow down your site, as it does not take up much resource. Not even when you are inserting large amount of sliders with complex content. The issue you are facing is most likely server related. Unfortunately since you do not have any LayerSlider slider on the URL you provided, we couldn't check on it.
In any case, LayerSlider offers multiple options (Advanced tab) that you can utilize to increase performance. The conditional script loading option will only load the scripts when they are needed. The include scripts in the footer option helps with eliminating the render-blocking scripts. The slider markup caching option spares server resources and lowers database connections. Please also note that the caching is not present for logged in admins, so you might not see the difference on the back-end. There is also the Optimize for mobile option in the Slider Settings -> Mobile tab (hidden by default).
