So, when I was going 10x10 flax field it was okay.
When I expanded it to 36x36, it was all the time okay, but when I started to use barrels, because seeds couldn't fit inside my inventory and I was tired to half cut & replant field each time, half of it started to slow down extreme.

Taking that quote as a base investigation, it seems that if You put seeds into empty barrel, and use them to replant a minute later, this starts to happen.
I mean, these seeds came from the same time, was replanted it minute or two of difference, with shouldn't make such huge difference, right?
So, if You want to play with that @jorb, I would recommend to:
Make a field that is half planted from hand and half from barrel. No mixed seeds, everything from the same source.
edit, proof:
