Hi Cameron,
This is fixed (or at least committed at github).
I did not quite find the source of the change. However, there was an unload/reload operation happening per time point, that had started making NIFTI float datasets get re-read from disk. That might have been an attempt to free memory as volumes were processed, being careful in case float data had a scale factor to apply (so no MMAP). Anyway, it is fast again.
Thanks for letting us know, and for the useful demo data!
