With a large definition file (150+ models and resources) there is a noticeable lag when I am typing in input fields. The issue is most pronounced on IE.

Issue appears to be similar to what was reported in #4057 however the plugin workaround doesn't address the issue. The console log does report 'render' for each key press but the early return doesn't improve the performance the way it was reporting in the original issue.
