Performance Issue with "Nop Ajax filter Pro"

We have 10Lakhs products. We are using “The Ajax Filter Pro Pack” wherein combination we are using is “Category & Manufactures and Specification”

The challenge is we are facing a huge wait time of 15 seconds to filter and display the products.

We need to resolve it and bring it down to 2seconds as its effecting our customer experience badly.
Kindly reply or reach out to us at "[email protected]

Thanks In advance
