Hi Jonathan, +1 to that list for me.
In my experience JavaFX performs well for the "low-level" (Canvas + GraphicsContext) stuff with one exception - the PixelWriter APIs appear do a lot of array duplication and copying under the hood which I believe can be optimised. I'll investigate further and try to come up with a patch. Nice to have (but lower priority than everything on the list) would be a public API for grabbing frames from a MediaPlayer which used to be possible in 8 with player.impl_getLatestFrame(). Echoing Tom and Felix, my #1 priority would be fixing scenegraph performance as tables with large row counts and charts (e.g. XYChart) with large numbers of data points (e.g. 50K) in their Series can easily lead to multi-second render times and huge heap usage.
