It looks the bug from http://www.devexpress.com/Support/Center/p/B139812.aspx is back, or at least something similar.
A ASPxCombobox lookup column with a large number of items causes a significant slowdown. See the 2 test projects using 9.3.3 and 10.1.4. Page through the gridview. The label below the grid shows the callback time.
This is a simple example but the difference is 2-3 times slower. I my real world project the performance difference is at least 10x.
Thanks in advance.
