The information provided below is independent from any tool chain and any platform. It's about static memory allocation required to support Agnos Framework (there is no dynamic allocation as per coding pattern). Hence, it presents RAM consummation benchmark established from the following system parameters (see Appendixes):

...

NOTE 1: These values are given as a examples and can change versus platform
NOTE 2: The following table uses estimates for the Win32 MinGW Platform with a GCC compiler using Release Optimizations
NOTE 3: RAM column only estimates Heap Memory consumptions
