    We are trying to chart a trend for a year's worth of data (approximately 340 points) over 3 series, so a total of ~1000 points on the chart.  Rendering in the Telerik MVC Extensions took less than a second in Chrome, but the JavaScript initialization takes 5-7 seconds with the new controls.

    We primarily work with IE8 (hopefully changing in the next 6 months...).  A few hard numbers:
    - Telerik Charts rendering the above scenario: 3 seconds
    - Kendo UI charts rendering the above scenario: Ran for 3m30s, threw out of memory error.

    Is there any way to increase the rendering performance of the charts, other than decreasing the number of points?  If not, does Telerik plan on bringing back the old way of rendering the charts?  This is really, really poor performance.

    Thank you for getting back to me so quickly. Is there a timeline for the release of the next version?  If it will be a while we will need to start converting our charts back to the MVC Extensions.

    Hi Tom Jacoby,
