Try the attached minimal script taken from Jens' original example.

In Octave 3.2.4 it takes on the order of 2-3 milliseconds on my system.

In Octave 3.6.4 it takes about 0.25 seconds.

In Octave 3.8.2 through the latest it takes about 0.33 seconds.

running that script with the 3.2.4 version of legend.m linked above, I get the following error on line 8:

warning: legend: plot data is empty; setting key labels has no effect

    legend at line 167 column 7
