F5 will maintain the session for as long as the TCP session is active - this will depend on the setting in the TCP profile.

 

Without a persistence profile, users will always go to another pool member when the TCP session has been cleared which may have undesirable results with the application.

 

Moreover, using Least Session LB algorithm without a persistence profile (that uses the persistence table) will not load balance as you expect as it uses the persistence table to make load balancing decisions
