Lagging on the products pages.

Not sure if this is the right section to post or should it be the How to page since it is abt lagging.

These 2 pages lag on my site.

Even when I am browsing the pages on my phone, they lag too when I am scrolling upwards or downwards.

Soorry, I should have been more clearer.
My computer is not laggy. It is only when I am scrolling down to up or up to down, it feels slow. Other webpages does not feel that way.

I found a way to explain. Please compare the scrolling of the 2 sites.

There is a big difference, right?
