There's a nice explanation on OSX memory management in this thread:
OSX uses advanced compression techniques for memory, and keeps a bunch 
of items in 'inactive' RAM, so real 'free memory' is a bit difficult to

My experience is that Scribus itself is dieting on my memory (total 32GB 
RAM in Linux); importing an 32MB EPS into an image-frame and rotating 
it, eats away meager 124MB of my RAM.
This is fairly consistent with a "rule of thumbs" I read about 
somewhere: that many graphics applications need a triple of 
*uncompressed* data to work well; one 'active' copy, one in undo-buffer 
and one on disk. Don't take my words for an explanation of this though. 
Since I'm using an SSD, my swap-memory is not on a disk, but in RAM.

I've rarely used EPS-files bigger than 500MB in Scribus, quite possibly 
the application will grind into slow-motion at some point with such big 
But as ale said; the number and complexities of shapes, plus the number 
and complexities of operations done on them, will certainly jack up the 
memory usage. Just importing/resizing into a frame shouldn't be a big deal.

Would be interesting though to see some numbers on this (htop) for Mac
