The C++ source file SWIG generates is rather large and it takes GCC a
while to deal with it.  I don't think there's much we can do about
that (the SWIG and/or GCC developers might).

That'll have debug information in.  If you don't want that, installing
the files with "make install-strip" should remove it.  But it's not
actually a problem usually - the VM system loads pages from shared
libraries (and executables) on demand, so if the debug information
isn't used, it doesn't occupy RAM.

Incidentally, the .o file is just an intermediate file for building the
.so.
