[Fabio]

Follow-up Comment #7, bug #61259 (project octave):

the updated test script is 


agt=available_graphics_toolkits;
v={'on','off'};

for n=[1e5 1e6 10e6]
        fprintf(1,'\nnumber of points is %d\n\n', n)
        x=linspace(1,2,n);

        for k=1:length(agt)
                close all
                graphics_toolkit(agt{k});
                fprintf(1,'toolkit is %s\n', agt{k})
                
                for j=1:length(v)
                        if strcmp(agt{k},'fltk') && strcmp(v{j}, 'off')
                                fprintf(1, 'skipping test for %s where 
visibility is off\n', agt{k})
                                continue
                        end

                        fprintf(1,'figure visibility is %s\n', v{j})

                        figure(1,'visible', v{j})
                        subplot(2,1,1)
                        plot(x,x)
                        subplot(2,1,2)
                        plot(x,-x)
                        tic;print('test_large.png');et=toc;
                        %tic;saveas(gcf,'test_large.png');et=toc;
                        fprintf(1,'printing of png took %f seconds\n', et)
                        %fprintf(1,'saveas of png took %f seconds\n', et)
                        tic;print('test_large.pdf');et=toc;
                        %tic;saveas(gcf,'test_large.pdf');et=toc;
                        fprintf(1,'printing of pdf took %f seconds\n', et)
                        %fprintf(1,'saveas of pdf took %f seconds\n', et)
                end
        end
