I generally set this equal to the length of time that you cache a persistent state on the web-server. The value is how long the Connector for LVS should remember which server it sent a person to. If another request comes from that same source then the Connector will forward them on to the same virtual server. In that way, you can have persistent states that exist on a single webserver for each user, and each request always goes back to the same server in your cluster. If that doesn't shed any light on it for you, then let me know and I'll be happy to go into more (or less) detail.
