Please help :| RB5009 with 2.5G Advertise allowed, dramatic speed decrease

I connected my CM3000 directly to my laptop and speeds were 1444 Gbps with an Upload of 200+ Mbps.
Connecting everything back how it was, with 2.5G being advertised I am achieving 400-500 Mbps however my upload is 200+ Mbps.
With 2.5G removed from being advertised, I am achieving 920-40 Mbps.

I attempted to look at this post to try to replicate what was done: http://forum.mikrotik.com/t/hw-offload-on-lan-ports-not-working/163343/1

I added a second bridge named bridge-wan with the same MAC Addr as the first bridge.
I then went to Bridge: Ports: and added a new one specifying the interface as WAN and bridge as bridge-wan with Hardware Offload set to off.
Traffic on Port Ether1 seemed to have stopped.
So I removed everything I did.
I just don’t have the technical experience to figure this out.

Can anyone lend a hand?
