Examples of how the number of items in the list affect form performance (switching from 3 items in the list to around 220ish) can be seen in the test form (a single select1 control) I've created and attached.

Performance test form:

3 item list:

Loading time: 3-4s Show list options: <1s Select list item: <1s

220ish item list:

Loading time: 19s Show list options: 3-4s Select list item: 6-7s

Tested using IE7/XP and IE7/Vista.
