In trying to quantify the impact of a new content type on the Second Life grid, it’s necessary to look at both the statistical data, as well as getting an impression of things ‘on the ground’, in-world.
It’s now four weeks since Second Life’s Mesh features went live with Viewer 3, and while it would be good to get a few more months’ worth of data, it appears that the new Mesh content type has had less impact on the Second Life grid than any other new content type that I can recall. In fact, it seems statistically insignificant.
