Run ensemble (GA version in this case) as an applet with the console up. Note that it is sluggish. Try the stock chart example, it shows a lot of visual artifacts as it scrolls. Now close the console, performance is noticeably better.

Also, the performance of the console itself is poor. Clicking on the scroll down or up arrows shows very slow scrolling. Also, the mouse cursor is incorrect.

Jasper suggested using either a listview control (which would use a list of strings as a data model) or webnode instead of the current text control.
