Yes - I absolutely agree about that precompiled headers would make a huge
difference, lot more than anything else, and given support for precompiled
headers is a realistic job which could be done lot more easily, I think we
should focus our performance discussions on this topic.

The ROI (Return On Investment) of working on precompiled headers would be
huge compared to other changes we might develop.
