	Using visual micro under both visual studio 2008 and 2012, I find that the avr compiliers are always called with the -Os switch (optimise for size) Is it possible to get visual micro to use the -O2 or -O3 optimisation switches instead? Using a Mega 2560 so would like compile more for performance that size. Clearly I can do this sort of compilation manually, but would like to know if it is possible to set different compilier options in Visal micro. Thanks

	Hi Tom, If you are using the Arduino 1.5.x system then the build process is entirely defined within the config files which you can easily extend or change. It is quite easy to edit the existing config in arduino/haradware/arduino/avr/platform.txt or if you want to preserve Arduino "as is" there are many options but the simplest to describe might be to copy the arduino/haradware/arduino/avr folder then edit the boards.txt to contain only one 2560 board with a unique name and then edit the platform.txt In platform.txt you will find the compiler switches
