Webpack 2 Dynamic Imports are Very Slow #2176
Description
While we officially support dynamic import() proposal, it is reported to have significant build performance issues (#2172 (comment), webpack/webpack#4636).
We are going to de-emphasize their support in the documentation until Webpack fixes them. I will disable the require.ensure deprecation, and will track re-enabling it in this issue.

Setting this up as needing contributions. Specifically, we need somebody to help Webpack folks in webpack/webpack#4636 reliably reproduce the performance issue.
