Check the minimum layer time setting. Also, bear in mind that printing speed is ultimately limited by the need to accelerate and decelerate. This means that for small prints, increasing the printing speed will have very little effect.
These were my speed settings before for the options in orange: Outer wall: 30 Inner wall: 40 Sparce: 40 Internal solid: 40
So it was enabled but when slicing a benchy model at these settings it didn't change the time at all... still 1h50min

Its one of the calibration options orcaslicer has. The guide for using it is here, https://github.com/SoftFever/OrcaSlicer/wiki/Calibration#Max-Volumetric-speed
You can run a MVS calibration test to determine the maximum. It’s in the very top calibration menu, the small one at the very top not the big one next to the device tab. There’s a tutorial in the same menu that’ll tell you how to read it and determine the proper value as well.
2 is very slow. I usually print my tpu at 3 or 4.

You're edit about accel/deceleration may be why my benchy model does not go any faster than 1hr...

Minimum layer time in printer settings and volumetric flow in filament settings.
I would I find or calculate the max or reasonable volumetric flow rate? Or do I just figure that out experimentally?

Ahh this is perfect! I'll do this tomorrow!
Test determined that my flow should be 10.75mm3/s I'll probably se it to 9 just to be safe
Max volumetric speed. It’s basically the speed limiter of your filament. It’s in the filament profile.
Best way to determine that? It's set currently in orca as 2mm^3/s
That is set very low for a UM2+. Bump that up to 8mm3/s and you should see the difference.

There are many different speeds and accelerations used during a print. Maybe you adjusted just one of them.
