I like to look at LACP this way..... Its used for failover if one link goes down, you dont lose your connections. Or you have it configured as a single interface, in that its just like the highway you drive your car on. Speed limit stays the same, your just adding lanes so more cars can travel down the road at the same time. If you're after more speed, you need to upgrade your network to 10Gb. LACP wont make anything faster, it will let you just have more links running at gigbit speeds without bogging down others. At least thats how I understand it, in a dumbed down kind of way.
