Looking at the profile, Athens spend time on some of my widgets: 1. LabelMorph with a workaround in the draw method as: drawOnAthensCanvas: aCanvas "Work around for the conflicting size font problem"    aCanvas pathTransform restoreAfter: [    aCanvas pathTransform scaleBy: 1.00001.       "draw text here"       super drawOnAthensCanvas: aCanvas]. Do we still need to do that, may be not. 2. TextMorph with another workaround: drawOnAthensCanvas: aCanvas    | cached |    myForm ifNil: [myForm := self imageForm].    cached := aCanvas cacheAt: myForm ifAbsentPut: [       myForm asAthensPaintOn: aCanvas.   ].    aCanvas setPaint: cached.    aCanvas paintTransform restoreAfter: [       aCanvas paintTransform translateBy: self fullBounds origin truncated.       aCanvas drawShape: self fullBounds]. It should be faster but it is slower. 3. PointMorph, painting as round shape is slow, painting point as square is way faster. It reduces by 50% the time to execution. Need to check if this trick #1 and #2 are still needed at P7 time. Hilaire Le 04/04/2018 à 22:31, Hilaire a écrit :
From the profile, there are a lot of activities with Athens. I can't say if it is normal... Someone with good knowledge could dig on it. I can provide the environment to test.
