preview, insane RAM usage
hello,
i am currently experiencing problems with preview.app, which i use as default for viewing PDF files.
i got a pdf with some lecture notes (hand-written scans), which is about 270 MB of size. when working with it (scrolling through it, reading, scrolling back and ahead) the OS nearly comes to a halt, which i tracked back to the insane amount of RAM that preview is using:
as i said, the pdf is quite big but as i have 8GB of RAM it should be no problem at all to keep the whole file in the main memory. there are no other opened applications but terminal, twitter, activity monitor and mail.app
all in all, 7.77 GB of RAM are stated as "used", where preview uses 6.50 GB of "real mem". and as i scroll through the pdf (which scrolls smoothly) the RAM usage just goes up and up (until swapping starts and stuff becomes incredibly slow).
any ideas ?
