Slow flow refrigerator dispenser questions. Plumbing

My refrigerator water dispenses 8 ounces in 40 seconds.

The pipe to the fridge flows at 8 ounces in 8 seconds.

Here's how it's currently plumbed:

Saddle Valve into copper pipe. 25 foot 1/4" pex pipe to fridge

Is the issue inside the fridge or in the plumbing? I know saddle valves are the worst but is that the source of my issue? Is the flow from inlet pipe fast enough?

Thanks for any help.

EDIT: Fridge Model is: Frigidaire FFHS2622MSU
