That's exactly what I've run into - the memory issue using packages and I'm
loading/unloading at runtime. I
I'm very much the same situation as you with VCL, IBO, Report Builder, Raize
and a couple more.
I've also run into the resource issues on Win 9x - invalid Win32
application.
This is all why I am looking into DLLs. My exe is over 13 mb with runtime
packages.
Ugh...seems like there is no good/perfect solution.
Thanks for the reply.

Not sure about examples with DLLs, but a related note...

It is generally much easier to modularise using runtime
packages - BPLs (which are just special DLLs). Its the way
Delphi/BCB is designed to be modularised.

The downside is that the app will use significantly more
memory - if I remember correctly one of my apps used something
like 12-15Mb more RAM when running using runtime packages as
opposed to running as an all-in-one executable.

But then that example comes from a library using runtime
packages for the VCL, IBO, DreamComponents, ReportBuilder and
my own packages. So your situation may vary. I ended up
going back to an all in one - which meant it could run more
efficiently on terminal server (but not at all on Win9x
because I ran into resource issues).

With runtime packages you dont generally need to worry about
issues such as connection handle sharing - although there
again it depends on exactly how you implement.
