I have Configurable products with 1000's color options so that page is taking much time and simple page is not taking so much time.
I think all simple products are calling on the page that's why it slows down so please suggest to me how to optimize loading time for the page.
Please check the below screenshot for the Configurable products.
Thanks : )
You can enable the flat catalog product and flat category from the backend. to do that go to store > Configratation > catalog > catalog expand the storefront tab and select the flat catalog and flat category as yes.
You can do the customization for the options display. set read more feature after clicking on that more color options will display.
