I understand what you are trying to do and why. I just wanted to point out that maybe the gain could be very little if the flash memory speed is high and that it could be bigger by launching a program that uses those libs. Maybe adding LD_BIND_NOW=1 to that program to force the linker resolve all the symbol could be worth trying. Anyone has raw numbers about the speed of internal flash memory? My 2c again. Alessandro
