hello!
great website!
the most important thing here is that you turned on lazyloading, which you did, in lay options → carousel addon
Sometimes it's not too bad, but sometimes it will take 30+ seconds to load all content.
Is the whole website taking 30+ seconds to load?
Or just the content of one specific carousel?
for me it loads really fast, i use chrome
i refreshed the page 10 times now and every time it loaded really fast mmh
