Thanks Steven, that would be great. We'd certainly be interested in trying what you've got on Fusions compile time performance tests.
Thanks to everyone else that provided ideas on this.
Remember that although the number of template instantiations is important, it doesn't necessarily have a linear relationship to compile times. I think measuring time is still important, and probably more important.
Absolutely. If we had a way to determine how much time was spent instantiating each template, it would be more better. Unfortunately, the time it takes to compile a whole translation unit is not very useful for isolating specific templates to optimize. The time does provide an excellent way to measure how much good any particular optimization did--once we have an idea of what to try. In Christ, Steven Watanabe
