"A script on this page is causing IE to run slowly" error when I use DayPilot

Asked by Joe Letizia

Has there been any report of DayPilot running 5million+ script statements? I actually have everything set to use postbacks, so I'm not even sure what scripts are running.

The IE performance when loading a lot of events has been improved in the latest release (7.2):

The event loading (parsing) has been optimized and the effect is particularly visible in IE.

However, if you are displaying a lot of events on a big screen it may take a lot of time to render everything. There is some room for optimization (choosing the best loading/rendering model) but you can't beat the browser limits.

Compare the performance of the following three demos:

You can try the following:

  • Make the visible area smaller by adjusting the dimension of the control (HeightSpec + Height, Width) or by making the cells bigger (EventHeight, CellWidth).
  • Show a smaller number of Days.
  • Try to switch to the CssOnly mode (it renders fewer DOM elements).
