How to speed up pcolor and waterfall for large arrays?

I have an array of size 32000x1000 and when I run the pcolor or waterfall function (I’ve also tried contour) it takes AGES. like upwards of 2-3 minutes to plot then save the graphic. is there a way I can downscale or something to speed it up?

Initial concept:
originalData = rand(32000, 1000); % Example large dataset
factor = 10; % Downsampling factor
% Downsampling
downsampledData = originalData(1:factor:end, 1:factor:end);
% Now plot using pcolor (or any other plotting function)
figure;
pcolor(downsampledData);
shading interp; % Makes the plot smoother by interpolating between points
colorbar; % Adds a color bar to indicate the scale
