Think of a tab panel with deferred rendering. You may still need to resolve components that haven't been rendered yet.Mitchell Simoens @SenchaMitch

It's just another technique to have in your arsenal. As ever, the only golden rule for optimizing is to take some meaningful measurements before you do anything else.

It's been discussed a number of times
@skirtle, thank you! It is nice to know that the idea makes sense at all and even implemented and works.
I will bear in mind that approach to instantiate components in a beforeRender listener. Thank you again.

We have some pretty heavy grids that have extensive templates in the main column to give the user a really nice view of a lot of data in one hit.
So, for performance, what's quicker; a templatecolumn (which would likely require more fields on the grid store to pre-format the data nicely) or a renderer that creates a data object from manipulations on the store on a per row basis and applies an xtemplate on it?
I suppose nested within this question are a few other performance details - like what's quicker, a convert function on a store field or manipulating the store data for each row before applying the template?
