To add some inputs to the above,
The parameter rec/client accepts the following values
rec/client OFF (Default)
rec/client ALL (All Clients)
rec/client 100, 200 (Specifying Client Numbers)
Since the table logs are switched on primarily in PRD Servers, you can just maintain the client numbers instead of all which will help you a little bit in overcoming performance issues.
Even we have that activated and we didnt see much of performance issues.
