Large file size of tud_logo.pdf
The TU Darmstadt logo (gfx/logo/tud_logo.pdf
) is 1.34 MB in size and makes up a large part of the entire generated PDF. Since it consists only of vectors, it can easily be reduced to less than 125 KB without any loss in quality.
I've re-saved it in Affinity Designer Adobe Illustrator as PDF 1.5 (the highest version LaTeX does not complain about) and attached it here: tud_logo.pdf
Maybe someone can incorporate the shrinked version.
