It does not. This is called up-sampling and merely adds bloat to the
files, as you have experienced slows down scribus a lot. Up-sampling
photos can be tricky and takes time to make it work. 300 dpi is more
than sufficient resolution for photos, unless you were printing to a
very high resolution device like printing for a high-end art book.

Use 600 dpi, automatic and Maximum Quality in the PDF Export and leave
downsampling unchecked. This will give you maximum quality with your 300
dpi pictures without unwanted file or PDF bloat.
