For the larger file, it's currently coming out to 4.82 days, but of course will slow as well (currently n=~124400, switching between ~20 and ~27 seconds with switching between 6K and 7K FFTs).
I think it's still too early to tell if the files are too large or not.
OK, then I expect you to figure exactly what it will take assuming that the LLR time increases by the square of the n-range. lol

It's actually more complicated then that and related to FFTlen jumps but it should give a close estimate because over the long run LLR time DOES increase with the square of the n-range. I'll have a try at some calculations.
