Thank you for the reply.

One more problem is that my controller is not able to fetch all these table details and display them in the controller UI. After fetching about 150 table details, it stops and connection between them gets idle.
Controller UI shows the switch, but not any details or flows or groups.
Even though I can see all details in command line, controller UI is not showing any details. That was also one reason I thought of reducing the number.

Reducing the number of tables available won't improve the performance.
