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?
