In my mps-multiline language (https://github.com/slisson/mps-multiline) I create a cell for each word. If the text contains 1000+ words and therefore the collection cell of the text has the same amount of childs, the editor performance is bad.

Luckily, it's not a big problem and can be fixed very easily. Here is my proposed solution.

The performance is bad if the editor contains a collection cell with …
…a large amount of childs (>1000). This change improves the performance of the biggest bottlenecks, so that the editor is responsive even for 1000+ childs.
