Hi!
Together with Santiago and Doru we have been working on a necessary refactoring of the Mondrian rendering engine. This is a prerequisite to make Mondrian generate HTML5.
I would like you to shout if you notice a slowdown with a large visualization (e.g., DSM, PackageBlueprint). I used it with large Hapao visualizations, but I was happy about the result.
Cheers, Alexandre
