Refactoring is your friend / moving from 6.x to 9.x

This is largely due to unicode support in everything, as I understand it. This performance hit is, I think, completely understandable. But there definitely is/was something else going on when developing under Windows. As other threads have amply demonstrated, V9 introduced a massive performance hit, and it's my understanding that those issues have been somewhat or wholly addressed in 9.0.2. 

I will be corrected if inaccurate.

This pretty much negates the benefits of Moore's Law (and similar advances driving current and future hardware) and deprives coders and users of what would otherwise be a trend toward (offset a bit by OS flashiness) general 1.x improvement in performance over time. And that's passive gain; any work on code improvements would yield a multiple of performance.
