Tips from Kenny after his research:

I did some research myself and i found the slowness is being caused by a for loop in certain function :

  • in the selection plugin (plugin.js )
  • in the function getBoundaryInformation

There is a for loop there, which seems to go over every node in the editor and check on nodetype = 1 ( element node ).

However, in the case of entermode br, the node there is not an element node. If you follow the for loop, you will see that in that case, it does not perform a return. As such, it will go over the for loop.

The result is that, the more you type, the more nodes, so the longer it takes to execute this function.
