Unfortunately this is true. :-(
We managed it to spend less memory that StarOffice 5.0 but
it still needs quite a lot.

I am happy to be able to tell you that 'facts' being told
to us above are not right.
Of course StarOffice doesn't use that amount of memory!
At the very moment now while writing this mail i had a
short look at 'ps -m' ('top' resp.) and laughed when seeing
the number of 9 (nine!) entries of 'soffice.bin'. By opening
some other tasks within StarOffice i could easily have that
number increased even more - with each of them pretending to
consume 35 MB.
The simple reason for the common misunderstanding of that
phenomenon and for lots of trouble is that some people start
writing their ideas and theories down without having ensured
that they are true!
StarOffice doesn't consume that Mem for each 'instances' because
there AREN'T ANY MULTIPLE INSTANCES - even if it looks like that.
Instead of this StarOffice runs multiple THREADS (not instances)
to improve performance and all of these threads of course use
THE SAME MEMORY.
The stupid fact that 'ps -m' or 'top' don't show this clearly
caused *some* people to call us by phone and complain about that
Mem Vaste they seemed to have found there.
Work is not always easy for my colleagues of the Support... ;-)
