Answer 1

There are several ways to load data into the databound components... DataSource is quite powerful and is a good option when using very big data sets.

If you use a DataSource, make sure not to load the complete data in one request and let SmartGWT load the data on demand. Also there are several options that can have an impact on performance on large datasets.

use dynamic loading:

myGrid.setLoadDataOnDemand(true); // good

do not use autofit rows as it requires to render all the rows:

listGrid.setAutoFitData(Autofit.BOTH); // bad, just let it on default

do not try to render all data at once:

grid.setShowAllRecords(true); // bad

and the last option: you simply created an endless loop ;-)
