Swapping a Router with ASA 5506

I recently was at a job site were I was supposed to swap a Cisco 1941 with a ASA 5506. I preconfigured the ASA and tested to make sure it was routing outside properly. There is a Verizon business 300mbs line coming in to the Router. When doing a bandwidth/speed test on Verizon's website I got around 130mbs to 140mbs with the router. I did some research on the router and discovered that the max was 150mbs so 130-140 is fine. When I connect the ASA to the same line, I get anywhere between 15mbs-40mbs. The ASA isn't doing much and I added a global ACL to allow anything just to see if that was the problem.

The original setup with the router was a typical router on a stick with sub-interfaces routing for each vlan, and the swith doing only layer 2.

When I connected the ASA, I created SVI's on the switch to let the switch do the vlan routing and used the ASA as the border router. Everything seems to be routing properly but the bandwidth has dropped significantly. Any help or suggestions would be apreciated.

Here was the planned setup for the ASA.

I would initially check your ASA ports are running at full duplex and there are no errors on the Interfaces.
