Hi all,
using the tool jvisualvm, i found the bottleneck. This is the method 
Grid.getIndexOfItem. It calls the indexOf method of the collection items which 
have low performance in the collections of large amounts objects. Avoiding this 
method, there was a significant increase in performance.
Happy Easter to all.

Hi,

Mirko has solved bug 385300 [1]. The Grid widget can now easily handle a 
million rows with a thousand columns each.

Thanks Mirko.

Cheers,

Wim
