assuming the test is the full version,
the first run is longer but after that the libraries are loaded
I have:

bAfter =  1
Elapsed time is 1.4038 seconds.

Cygwin 64 running on W7-64 bit from octave-cli on a

FLTK and Gnuplot are roughly in the same ball park +-5%

Considering the drawing it seems fine.
