Details:
This seems odd. I ran the following test sequence
Development branch, cset 23116:868daa374c49
run-octave -f --no-gui-libs
tic; demo ('axis', 1); toc # first result is unreliable because of
initialization
tic; demo ('axis', 1); toc
tic; demo ('axis', 1); toc
tic; demo ('axis', 1); toc
The graphics toolkit used is FLTK, and the time is ~740 milliseconds.
Running the same sequence with the stable version of Octave
octave-4.2.0 -f --no-gui-libs
tic; demo ('axis', 1); toc # first result is unreliable because of
initialization
tic; demo ('axis', 1); toc
tic; demo ('axis', 1); toc
tic; demo ('axis', 1); toc
yields a time of ~290 milliseconds.
