Illustrator EPS files at the moment ;-(

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
