I take it as a good sign that the categories “Performance” and “Quality” have not seen a lot of submissions in the “Missing Features Survey”.

Performance

In the survey the performance of JavaFX was compared with the performance of Swing and people noticed that JavaFX is slower than Swing. I personally have yet to find a use-case where that is true but I do believe that they can be found, however it should be noted that JavaFX also provides a much better coding experience based on a modern API and architecture. JavaFX supports property bindings and CSS styling. These things of course do take their toll on CPU time. Swing was designed for computer hardware that existed 20 years ago. JavaFX is targeting today’s hardware.

Something that I can agree on is that the use of huge quantities of more or less complex controls within a single stage does lead to performance issues. In a test case that was discussed by several JavaFX experts in Germany, Switzerland, and Austria we looked at the performance of JavaFX when displaying several thousand textfields. This does sound silly but there are use-cases out there that need to create this amount of controls. Whe
