Performance impact drop-shadows

Has some body experience, proof or an opinion on the performance impact on multiple drop-shadows?

Some in our team complain about slow file rendering. And we think one of the reasons are the drop-shadows. From web development I know that large shadows are slow to render. But is the same true for multiple stacked drop-shadows? The Designer working on the design system uses 4 shadow layers to get the perfect shadow.

Does someone has a performance test or performance analyses to see the impact of multiple shadows over a simple shadow layer? — Maybe Figma can add similar to the Memory Usage, a performance Chart to see what takes up rendering time.

Hey Phillip,
Sorry to hear you are having issues with a slow performance in your file!
Hmm to be transparent, it’s hard to identify the root cause without investigating with the file directly.

This usually also happened when the percentage of available memory is low.
I’d recommend you to reduce your memory usage: here are some tips that may be helpful on our guide
As reminder, Figma is browser-based, and every browser has its own active memory limit of ~2GB per browser tab.

Be sure to use your Figma account email, include links to the file, and share it with support-share@figma.com so they can take a closer look. Thank you!
