As time goes on, the numbers from PCH will be more and more important 
to not regress, also the 2m slowdown will go from 20% to something like 
2x slowdown.  Some folks might be tempted to put in a 20% slowdown, 
but, they should have a harder time (from us) for a 2x slowdown.

So, adding a column with good PCH numbers would help prevent C++ 
slowdowns.

Thanks for your help.
