The collections client state will be stored in the view state and the client collections will not be sent from the client on postback. This is possible because client collections contain static data that does not change on the client. This data is used by the client API and when something is updated it is stored in the transactions list. If false the collections from the client side will be uploaded as before. Setting this to true, will increase page size in terms of view state, but will decrease the postback time numerously, because the collections state will not be uploaded from the client.
