Rev E. prints slower than Rev. D.

Well, I picked me up a used Rev. E. It's working great! However, it prints slower than my Rev. D. A print time that should take an 1.5 hours takes 2 hours.
I use the same FFF settings on both machines from simplify 3D. Don't know really where to begin to trouble shoot this. Any ideas?

The heavier bed was paired with slower acceleration. It's a firmware / GCode adjustment if you want to raise the speed back up.

Wait, I thought the firmware was in the machine itself. How would I update that?

It's one of the configurable parameters.
If you issue an M503 command, you'll get back the changable parameters. One of them will start with "M204" -- that's your baked-in acceleration. Copy that line, keeping the M204, and send it back with higher numbers. Use M500 to save.
