I think that this is a meaningless comparison, for the purpose proposed:
testing which system had more multitasking overhead. One has no
idea how the three different compilers arrange to use memory and io.
Unless there is a test of the output of the compilers, one doesn't know
how much work they did optimizing . Presumably if one wants to test
the multitasking abilities, what is needed is a program (or, 
preferably, suite of programs) which does varying amounts of io vs.
cpu calculation.
