I recently made some performance improvements to my backend and I decided to take it for a spin. 

I tried pushing out 1000 products with images it works fine on all desktop-based browsers, however it made the site crash on my ipad mini. Are there any best practices/performance-tests available? Mobile browsers have their own site and are not included.

To be clear: i don't want to solve the issue on my iPad, I want to know if there are any best practices for DOM-size.
