I have just upgraded my macbook air to Mavericks and I noticed now that Activity Monitor has an energy tab that shows which apps consume most energy and Pharo is on No1 spot for idle apps. 1) Pharo - > 50-60% 2) Chrome (7 tabs open) -> 10% 3) Blender (3d app) -> 15% emacs, itunes , maps etc close to 0% The only way to compete with pharo is playback a youtube video that spikes energy to 80 or play a 3d game. I assume Morphic is quite heavy on resources.
It took you a long time to upgrade, next month you'll be behind again ;-) Anyway, this has been reported before: http://forum.world.st/Pharo-on-Mac-OS-X-10-9-Mavericks-td4716590.html And even long before that: http://forum.world.st/Hungry-Pharo-td4717636.html BTW, it is not UI related as it is visible on servers as well.

Hello, I believe the issue is that typically on idle an application does not consume energy, it is in wait mode and restart when an I/O event is triggered. For Pharo, I/O event does not restart the Process, on idle, the Process waits for 1 ms, then checks if I/O event was triggered, and if nothing happened, waits again a ms. We wants to fix that in the future but it is difficult it requires to change the Process implementation which is implemented half in the VM half in the image .... I am not sure it is related to Morphic. 2014-08-10 20:10 GMT+02:00 kilon alios <kilon.alios@gmail.com>:

fair enough I wanted just to inform you. Oh and Sven I never jump to the latest version , don't want to have to deal with weird bugs and instabilities , I let you all be my guinea pigs , so go on and don't wait for me ;D. On Sun, Aug 10, 2014 at 9:50 PM, Clément Bera <bera.clement@gmail.com> wrote:
