Improving page creation performance

[Ramkrishna Kulkarni]

Hello Jesse,

I've noticed a considerable drop in performance as the number of Nitrogen elements increases per page. Below are results of some load tests. Do you have any idea how to improve performance here?

--- case #1 no elements ---

Hi Ram,

These are definitely things I'm looking to improve. I had been
meaning to spend more time optimizing element rendering in general,
but alas, ran out of time.

But indeed, improving element rendering time (without breaking
backwards compatibility) is on the list of the things to do :)
