Hello, I'm implemented an AggregateFunction (CountFunction) in my GridView, but that decrease the perfomance of the loading drastically. Without the CountFunction, the Grid loads very fast, less than a second, and when i add the function, takes about 4-5 seconds to load the data, and, when I group a column and remove the group, it will take some seconds to load everything again.
