Will OOP reduce the performance of the application.

I have to query 4 database with more than 1000 rows between each user inputs to give the output. The whole thing must be less than 5 seconds to the maximum extend and an average of 2 seconds. Which type of design is better for performance.

What does your experience tell?

Thanks.
