Looking at amd64, the Installed-Size of current packages are:
insighttoolkit3-examples 3888
libinsighttoolkit3.20 12964
libinsighttoolkit3-dev 26808
libinsighttoolkit3-java 41740
libinsighttoolkit3-jni 227656
python-insighttoolkit3 556020
tcl8.5-insighttoolkit3 377112
The first one is small. The second and third will be required (as
build-dependencies) to build the following ones.
The four last ones (the bindings) are about 1.2GB big. The biggest one
is 550MB big. It means that, on amd64, you will save at most 700GB but
your build system will be a lot more complicated (with multiple
inter-dependent uploads).
If you think that 700GB saving is not enough to split your package,
you can work on the build of your actual package to remove intermediate
built files between each parts.
I mean that you probably do something like ./configure ; make ; make
install ; dh_install ; ...
Perhaps, you should tried to modify your build system to do
./configure --only-corelibs ; make ; make install ;
dh_install -pcorelibs
make clean
./configure --only-python-wrapper --with-corelibs debian/corelibs/...
make ; make install ; dh_ionstall -ppython-bindings
make clean
./configure --only-java-wrapper ...
and so on
(package names and configure options are only examples to give you the
idea, I do not know at all how your package is build)
The idea here is that (the size required when building from one source
package) should be roughly equivalent to (max for each source package of
the required size) + (the size of all binary packages)
