Follow-up Comment #15:

Sorry for the long reaction time.

With the changes proposed in comment #14, I see approximately the same
performance that we had in Octave 5.2.0.

This might also improve performance on other platforms than Windows. But I
didn't see any significant difference on Ubuntu with or without the patch.

I pushed a change here:
https://hg.savannah.gnu.org/hgweb/octave/rev/2420f8f62ebe

Maybe, we could do something similar at other points in the code where we are
reading floating point values from a text input stream repeatedly.

Marking as ready for test.
