Do collapsible sections load fast enough to not annoy users?

As an e-commerce website owner, I'm considering adding collapsible sections to my product pages to improve information organization and user experience. However, I'm worried about potential performance issues and whether these interactive elements might slow down page load times or create a frustrating browsing experience. I want to understand the technical considerations, performance implications, and best practices for implementing collapsible sections that enhance rather than hinder user interaction.
