Noobie needs help with config

So I am wanting to use our new Mikrotik CRS317-1G-16S+RM as our new network hub. The previous trendnet 10G switch could not handle link aggregation for our new NAS. I want the switchOS to be as simple as possible. I dont need a bunch of special permissions or static IPs. I want it to work like an unmanaged switch except for using 2 of the ports for link aggregation. I had everything connected the other day, and internet speed tests were only getting a 10th of what they did previous. Not sure if something is set wrong. I pretty much left everything at default. Please help. I attached a network layout below. Everything connected to the mikrotik is 10G, through sfp+ to RJ45 modules.
