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.
