Please, check the attached page with a setup similar to what you have as a setup, except the data-binding of the chart. The page creates 100 sliders and the delay is around 2-4 seconds. Please, check the following screencast to make sure the results are correct - http://screencast.com/t/46G5zwIX8
Could you, please, incorporate the necessary changes so that the delay resembles the one that you are experiencing? Please, make sure that the page is still runnable without external dependencies - DB, Services, etc, to which I have no access.
