in v 1.9, I had a very fast loading before adding about 1700 sub categories. It usually takes about 2 seconds to load a page
After adding sub categories, "New Products", "Shopping Cart", "Categories", "Product" pages take over 15 seconds to load which is not acceptable to customers.
Does any one know how I can fix this?

I did the same thing in Nop 2.0 and no performance change, it works great.
