Thanks for the detailed reply.
I broke my app down and found it was taking about 2 meg for all the
controls/windows - the rest was due to my code or other modules. I'm
considering using a new design approach were I'll be using child windows as
containers for groups of controls - potentially there could be lots of these
windows - roughly how much memory does a window use?
Cheers,
jez.

Yep, there's a "PERLWIN32GUI_USERDATA" structure for every control and
window. This structure is chunky, and has references off to other structures in
it, such as window names, cursors, accelerator tables, NEM events, etc. It
could probably be optimized down.
The reason it uses more memory is that it supports and does more stuff. When
you're writing an application to do, say, a calculator, you know exactly what
buttons and windows you want, where you want them, and what you're doing, so
you can build your C windowing code around your final goal. When you compile
it, things get optimized even more by the compiler. With Win32::GUI there is no
"final goal" and everything the Perl coder could conceivably want to do has to
be supported, making it's footprint quite large.

Hi,
I've noticed that my app uses lots of memory on start up (35 M) compared to
other "similar" applications (around 12 M) I'm on XP. I've got lots of windows
and controls which are created at the start - is there Win32::GUI memory
overhead for each control/window? Or should I start considering this as some
sort of bug in my code?
Cheers,
jez.
