Can F5 load balancer disconnect socket after each transaction

1- What about the pool and persistence profile?

is there any default persistence setting?

2- What sort of data is being passed across the virtual?

tcp transactions passes on virtual server

3- The server-side will normally only close if the client side is closed - this is expected behaviour.

So you say that client has to close the connection and there is no configuration on F5 LB ? means how then we can load balance/round robin the transactions which are getting a persistent connection.
