[Octave-bug-tracker] [bug #66012] printing to the pdflatex device is slow

[Pantxo Diribarne]

Follow-up Comment #13, bug #66012 (group octave):

On my system I see the timings for the three operations
are 

tic; for ii = 1:10, system ('latex tst.tex'); end; toc   ## -> 0.140 s/call
tic; for ii = 1:20, system ('dvipng tst.dvi'); end; toc  ## -> 0.135 s/call
tic; for ii = 1:20, system ('dvisvgm tst.dvi'); end; toc ## -> 0.235 s/call

So 45 % of the time is spent preparing an svg image that will only be useful
if the user finally prints with the svgconvert tool. So, for an improvement of
a factor of almost 2, instead of storing the content of the svg file in the
cache, as we currently do, we may want to store the content of the dvi
(binary) file and let the gl2ps_renderer run dvisvgm only when needed.
