Description
Steps to Reproduce
<zk> <button label="any event" onClick=""/> <!-- 13.2 sec <div forEach="${[0,1,2,3,4,5,6,7,8,9, 0,1,2,3,4,5,6,7,8,9]}"> --> <!-- 3.7 sec <div forEach="${[0,1,2,3,4,5,6,7,8,9]}"> --> 1.0 sec <div forEach="${[0,1,2,3,4]}"> <div forEach="${[0,1,2,3,4,5,6,7,8,9]}"> <combobox width="50px" forEach="${[0,1,2,3,4,5,6,7,8,9]}"> <comboitem label="yes"/> <comboitem label="no"/> </combobox> </div> </div> </zk>
click the button
Current Result
the ui freezes after the button response depending on the number of comboboxes
500 -> 1s
1000 -> 3.7s
2000 -> 13.7s
scales roughly quadratic
Expected Result
at worst linear performance scaling (if at all needed)
Debug Information
during the first onResponse every combobox calls checkPopupPosition forcing a layout reflow
