The uncommented part was the one that was slowing me down, its a copy from SystemWindow, on a new image of Pharo consumption drops to 15% but still have issues with Nautilus etc.
latsabben at Slack also recommended caching which helped also
taskbarTask "myTask := nil." myTask ifNil: [ myTask := TaskbarTask morph: self state: self taskbarState icon: self taskbarIcon label: self taskbarLabel ]. myTask label: self taskbarLabel. ^myTask
Anyway I decided to port my project to C++ and Unreal Engine because I have many issues with Pharo speed wise
See my other post, in about an hour I moved your App from 55% cpu usage on my machine to 7%, only 1% above our 6% idle. We *do* need to address that minimum idle, but its at the VM level since in-Image profiling shows 90% time in ProcessorScheduler class>>idleProcess. So to me the Image seems not too bad performance wise
and stability wise with Pharo 5.
Well, you are talking about bleeding edge alpha software.
Plus many IDE features I miss like proper auto completion etc.
You've probably mentioned this somewhere previously, but in another thread could you leave us with a summary of what is missing from auto completion.
To be fair I tried to make custom gui with python and it was even slower in the past.
So its clear I need a high performance language + API, because I will be building a very heavy GUI (many more animations) and I would like also some fast 3d functionality too.
good luck with it. cheers -ben

taskbar was the problem, damn pharo gui is a huge pain in the hat.
How so ?

The images are PNGs and RGBA , 8bit

With DrGeo, I noted Athens is faster to BitBlt with bitmap operations (in my case, only scaling and displaying a From in a DrGeo canvas). Also, do your bitmaps come with 32 bits depth?
