Are you talking about compile time, test program execution time, or both?

Regardless, you might want to do some experimentation first to see if there
are meaningful differences between compilers. Since the regression tests
aren't designed for timing, they may execute so quickly that the time is
below the available timer resolution. We need to feel our way a bit, and
make sure we are reporting useful information.
