Would just like to say that:

1. WT is probably my favorite Microsoft product

2. Since this whole affair, the developers have apologized and corrected themselves which is usually unacknowledged in these discussions.

3. The developers have made a number of performance improvements since (most of which are in the latest preview release).

4. This episode is constantly retold and used to bully the developers even after these apologies and this has lead to one of the developers to quit (paradoxically one of the devs who after these posts made the most effort to figure out where the bottlenecks are).
