When you have a large program with lots of subprograms, to maintain
efficiency and make maintenance easier you use shared objects. These
shared objects are dynamically linked at runtime. Dealing with hundreds of
files takes time. Yes, there are hundreds, look in
/opt/openofficeXX/program/. So although objects are not loaded in memory
if they are not needed, their signatures must be registered when the
program starts. Coming at the same time that a graphic interface is being
generated, with its hundreds of widgets, a lot of cpu and disk is used.

I suppose it would be possible to make a version that is not modular, but
that would be considered bad practice and it would be hard to convince
them to waste their time doing it.

Cheerful regards,
