Hi guys!

I think that a small performance gain is not a *great* reason to recommend something. And really, this was not the most important reason for recommending against `@Template`. I think it's clearer to focus on the real reason, and not get into performance (we could argue against using any feature because of performance).

Thanks!
The rendering of the template itself is going from 5ms to 9ms, so I think you are not comparing the same thing actually in the first place (cached template vs non cached one ?)
