Hi Jeff,
Please add your weight to the JIRA (indicate the hardware you are
using). A fix for the desktop should also fix the problem on iOS.

I noticed the high-dpi problem on a high-end MacBook Pro Retina. Took me by
surprise for JavaOne demos since I usually use an external monitor
(non-retina). I ended up switching to low dpi.

Hi Tobias,
Sorry about that.
Looking at the bug, it seems to me that we have gotten to the bottom of it.
Some iOS devices are scrolling fine while others are slower. The difference
seems to be that high dpi disables optimizations and this causes the slowness
on iOS. The same optimizations are disabled on the desktop, but the desktop is
much faster and people don't notice. There was some discussion about
performance in the simulator, but we should ignore that. Performance on the
device is what matters.
iOS and Android are not currently supported platforms for JavaFX. We are
looking towards the community to step up and submit patches to take these ports
forward. Johan Vos and others are helping with Android. Are you interested in
working on iOS? If so, please build on the patches in
https://javafx-jira.kenai.com/browse/RT-31453 and take the work forward.
The first step would be to prove that we can be fast (which I think we can if
we run with the optimizations) then understand how to turn the optimizations
back on.

Hi,
many months ago I reported the „poor performance on iOS“ issue
(https://javafx-jira.kenai.com/browse/RT-31453). Now 6 months later the bug is
already open and no one of Oracle answers me on Jira.
What’s up? How can we fix this important bug?
Best,
Tobi
