I've also noticed that the calendar component has some performance problems
with IE. However, my performance issues have not been nearly as bad as
yours. I'd guess that I see about 1/2 second to a second delay for each
calendar on the page with a similar machine. Regardless, the slowness was
still enough to make me stop using the calendar component.
I've started using a text field and a free javascript calendar
(
http://www.java2s.com/Code/JavaScript/GUI-Components/FancyCalendar.htm).
There are one or two small modifications needed to the javascript calendar,
but overall it works pretty well. For instance, the window.onload sometimes
breaks the rendering of the woodstock components. Instead, the calendar's
init function needs to be called after the components have all been
rendered.
