If you have used the ZK 3.0.x version, you might find that the performance of
Grid/Listbox/Tree
with a large data(like many rows) is a sort of unacceptable, which ZK client engine needs to calculate the width of each cell. Especially in FF, even if ZK client engine just assigns a normal size to the TD
tag of a single row in a big Dom tree(like table), the computing time of FF still takes more time than IE after we optimized the Javascript code.Fortunately, we found a way how to sovle this bottleneck is need to shift a little structure of the Dom of these components. After we modified, we gain that the performance is many times faster than ZK 3.0.3.
