@jinu “normal” LAG that follows RFCs will only allow each point-to-point communication (or a flow as other mentioned) to go as fast as the fastest individual link you have in your bundle of links. Some proprietary LAG (like MC-LAG between physical chassis switch) will split the the flow among links but that is out of your control and will actually let you run a single flow at N x number of links you have bundled.
Else, you either tries to used different routing strategy on the LAG it self at layer 2 (MAC),3 (IP) and 4 (Port), or as in most big entreprise with tons of VLAN, you change your root bridge per vlan to control how STP will allow or block certain traffic on certain links. But that’s quite advance networking that need to be designed on paper before going full tilt on configuring the switch! But that will let you maximize link aggregation.
