Plotting has severely slowed down since sage-4.8.
For example the following command (inspired on a doctest from
devel/sage/sage/plot/plot.py):
{{{
sage:
timeit('''plot(sin(x),(x,0,2*pi),ticks=pi/3,tick_formatter=pi).save("/tmp/1.png")''',
number=1, repeat=20)
}}}
It's annoying to measure this as the timing has quite a large standard
deviation. But on boxen.math, with sage-4.8, the best case timing is
about 1 second, while with sage-5.0.beta13, the best case timing is
about 1.5 seconds.
