Performance - disable theme / other plugins

Hi!
we are looking a reason, why our page works slow. One proposition we received is to turn off all plugins, and try open nopcommerce default theme, and see how then all work.

I'm wonder if we chane our theme to nopcommerce default, we lose informations from Element responsive theme? Element using different size images etc. and i'm little afraid when we swap theme to another, it's can broke something?

Hi! i think we found a reason slow loading(third part widget).

We still work with performance and i have question:

Is it possible to add lazy loading pictures to your theme?
https://developers.google.com/speed/pagespeed/insights/?hl=pl&url=http%3A%2F%2Fthemes.earth1.element.nop-templates.com%2F

In our case this can give us possibility to increase speed about 1,8 s in category pages.

Hello,

Unfortunately, lazy loading the product images on the catalog pages is not supported by nopCommerce.

You can try to optimize loading of the images by decreasing the image quality or resizing the images from the Media settings.

Hi! ok, thx!
