Website started lagging - please help!

Hey everyone :smiling_face:
I have a problem with my Webflow site that I’m struggling with for over a week now, and I really need your guys’ help.

I am working with a template called “Colours” by Lucas Gusso.
I have NOT added any fancy animations, interactions, custom CSS or large files/images/…

For some reason, the site just started lagging out of nowhere.
It works perfectly fine on mobile, but on desktop it’s extremely laggy (see screen recording here)

Yes, I have cleared cache, run Lighthouse performance checks, tried on different devices and in an Apple Store.
Not even restoring from a backup from BEFORE the lags started solved the problem. :frowning:

I’m really running out of ideas and am stuck here.
Please, if anyone can help, I’d be extremely thankful and willing to pay for it!

Thank you so much!

If your Webflow site is lagging on desktop but not on mobile, even without animations or custom code, the issue could be due to heavy rendering caused by large DOM structures, unoptimized fonts, or resource-intensive components. Run a Lighthouse Performance Audit and check for large elements or unused styles. Optimize all images and assets, reduce DOM complexity, and remove any unnecessary elements in the template. Also, check browser console logs for errors and test the site in incognito mode. If the issue persists, feel free to contact me I’ll be happy to assist you.

Hey @CloudCoder
Thank you very much for your advise, but as stated in my original post, I’ve already done all of those things.

The issue persists, but only on certain devices.
For example, on my business partners older mac it runs perfectly fine, while on my new higher end one (as well as on new devices in the Apple Store I went to for testing) it’s lagging as seen on the screen recording.

Is there anything else you can recommend me?

That needs to be checked again, would you like to set up a meeting for that ?

Sure, I’ll send you my email via DM!
