Subject: Re: [Boost-users] Reducing the size of .obj file whichdoesserialization

My tests don't show the serialization consuming a disproportionate amount of
memory.

But I haven't made an application which serializes 200 classes either.

One interesting idea is to have the linker generate a *.map file (in release
mode)
to show the size of modules being created.

On a project this size, I would probably create it as a group of Libraries
just to make build and code management easier. If I build those libraries
as DLLS, then I can really see where the code is going. However,
this requires a little more care in organizing code to be sure that
only code actually used in loaded. This is sort of a pain - even
more so with the serialization library - but it makes a much better
final product.

Combining this with the polymorphic archive should result
in (almost) no code duplication. However, doing this requires
special care in seperating declarations from definitions.

And what does the release mode version come down to?
