That is important because it shows that CS 6 magaes memory better can access both the scratch and RAM better use more of it and is more stable.

well it took over four minutes but it ran out of memory and could not complete the preview where as in CS 6 I could do this again in the same document without the need to close it out but in CS 5 I would no longer be able to obtain a preview for that document no matter what I did. However I decided to see what CS 5 would do if the sqaures were arranged the same way. In CS6 I accidentally made a mistake the first time i tried this, and this is important, in which when making the configuration of squares I did not leave a gap between the squares which meant the squares where bigger, that time it took CS 6 2 minutes to complete the task.

In my test I asked CS 5 to apply the a drop shadow to 10,000 small squares that cover an 18 x18 inche area it takes CS5 3 minutes to do it but it takes CS6 1 1/2 minutes twice as fast. For instance i do a test for each new version to see if the performancce of my computer is the same for each version of Illustrator and do a different one for Photoshop. And Illustrator CS 6 runbs much faster than Illustrator CS 5.
