Actually, I just tried it with 1.1RC4 and it took about 7 seconds to initially add the benchmark shape file. After it loaded up, it did redraw in about a second. However, I was unable to get the table view to work on the file. I also was unable to get theming to work or even basic feature selection, so there may be some downsides to the speed.
Could someone more knowledgeable about uDig try the benchmark and see if it was just my inexperience causing these problems?
