Program memory usage in windows

[gerix]

Hello:

I have been using Qt4 on Windows for about four months. I had done a little Qt4 programming on Linux before that. I have noticed that Qt programs, even a "hello world" type application, take over 13 megabytes of primary memory. I thought it was related to loading a framework, but launching a second copy of the application gives a similar footprint. I was wondering what is using this memory. I was also wondering if there is a way to lower memory consumption.

I have searched online and I have not been able to find anything.

Are you compiling in debug or release mode?

Oops, I guess I was compiling in debug mode. When I switched the config over to release, it lowered the memory usage of the "hello world" application to around 6Meg.

Thank you for helping me.

Under Linux you can call "strip" on the binary to further reduce its size and memory consumption. Well... maybe not the "hello world" thing but a regular application.

Neat. I will have to try that when I get home tonight. Thanks again.
