Hi :) 
I think swap doesn't get used much these days.  Can you try 

free -m

before and during the process?  If swap is not being used even when it's in Ram then perhaps either 
stop using the ram-drive or increase swappiness?  I have 2Gb Ram but only about half that ever gets 
used and that's only when i really push the machine with games and video
Regards from 
Tom :)

I have a project managed by an odm file that ends up being ca 1600 pages

(even on such simple things as refreshing the window after remapping
it).  I've turned of recording/displaying changes,  upped the graphics
cache numbers, set the swap directory to a ram disk, and turned off all
to-disk swapping; nothing helps.   This is on a 2 CPU machine with gig's
of ram.

I'm currently trying  to print the project to a file (postscript
format).  This takes 4-6 hours, with 1 of the CPU's running at 100% [BTW
is LO multi-threaded?].  The resulting postscript file is big, (about
350M) but not that big.

I'm on a Slackware Linux box.

Any suggestions?


Which version of LO are you using?  That might help with some answers.

Have you made any modification the default settings of
Tools>Options>LibreOffice>Memory ?

I know that some people have seen some good results with the increasing of the different options 
for the memory usage for a document.  Large ones that has a lot of object/graphics/images could 
use more cache memoryand a larger "number of objects".  Then if you are not doing much editing, 
the reduction of the "Undo - number of steps" could free up some needed memory and response time 
for the document.

The 1600 pages long and many graphics can slow down any system, when you are "converting" the file 
to a postscript format.

By-the-way - what are you using for the print-to-postscriptprocess?  I do not see that as a 
"included" part of LO 4.0.2.  Are you printing it to a postscript printer but are saving it to a 
file instead of printing out to paper?  That process would give our users some idea on the process 
and my have some of the try some things that might find some answers.

I use Ubuntu 12.04 with 2 HP printers [inkjet and laser], 1 Epson inkjet, and 1 Canon inkjet.  
None defaults to a postscript, but the HP laser has a postscript driver.  I may install it and do 
some testing myself.

OK, I installed the foomatic-postscript driver for the laser printer.  It can print to a file.  
But would I need it to usethe "generic postscript printer driver" to make it device independent as 
you seem to want it to be by "printing" the file to a postscript file?
