How to remove these stitching/dimple textures?

I've been trying some new techniques to get higher quality prints out of this model. The first print had a lot of under extrusion and a very rough surface. I did some research and learned about ironing. So I tried it and it worked well. This model used 50mm at 40% with a spacing of 0.15 mm.

Is the ironing what's causing these bubbles/stitching pattern all over my top surface? My initial thought is that maybe my flow rate is to high? My other thought was maybe retraction or cooling settings needed to be adjusted?

Also, a side question: I'm at 9 hours for this print. Are there any tips or tricks to reduce this time without sacrificing quality? (Yes, I know ironing is adding a large amount of time) I was hoping to shave off at least an hour if possible.

Additional info: 0.12 layer height

Thanks in advance!
