Can anyone think of a reason why addChild would be very slow? I have some code like this: ```auto for (i=0; i<100; i++) { infoSprite = new CInfoSprite(this); CProfiler.start("addChild"); CCanvasManager.canvasSelections.addChild(infoSprite); CProfiler.finish("addChild"); } ``` The output from the profiler looks like this: profile ‘addChild’ took 14 millis profile ‘addChild’ took 15 millis profile ‘addChild’ took 17 millis profile ‘addChild’ took 18 millis profile ‘addChild’ took 19 millis profile ‘addChild’ took 19 millis profile ‘addChild’ took 18 millis profile ‘addChild’ took 18 millis profile ‘addChild’ took 20 millis profile ‘addChild’ took 20 millis profile ‘addChild’ took 21 millis profile ‘addChild’ took 20 millis profile ‘addChild’ took 21 millis profile ‘addChild’ took 21 millis profile ‘addChild’ took 22 millis profile ‘addChild’ took 22 millis profile ‘addChild’ took 25 millis profile ‘addChild’ took 25 millis profile ‘addChild’ took 28 millis profile ‘addChild’ took 26 millis profile ‘addChild’ took 29 millis profile ‘addChild’ took 29 millis profile ‘addChild’ took 30 millis profile ‘addChild’ took 30 millis profile ‘addChild’ took 32 millis profile ‘addChild’ took 34 millis profile ‘addChild’ took 34 millis profile ‘addChild’ took 34 millis profile ‘addChild’ took 36 millis profile ‘addChild’ took 35 millis profile ‘addChild’ took 36 millis profile ‘addChild’ took 38 millis profile ‘addChild’ took 38 millis profile ‘addChild’ took 39 millis profile ‘addChild’ took 38 millis profile ‘addChild’ took 40 millis profile ‘addChild’ took 41 millis profile ‘addChild’ took 42 millis profile ‘addChild’ took 43 millis profile ‘addChild’ took 42 millis profile ‘addChild’ took 43 millis profile ‘addChild’ took 46 millis profile ‘addChild’ took 45 millis profile ‘addChild’ took 46 millis profile ‘addChild’ took 46 millis profile ‘addChild’ took 48 millis profile ‘addChild’ took 48 millis profile ‘addChild’ took 48 millis profile ‘addChild’ took 48 millis profile ‘addChild’ took 48 millis profile ‘addChild’ took 50 millis profile ‘addChild’ took 50 millis profile ‘addChild’ took 51 millis profile ‘addChild’ took 51 millis profile ‘addChild’ took 51 millis profile ‘addChild’ took 52 millis profile ‘addChild’ took 55 millis profile ‘addChild’ took 53 millis profile ‘addChild’ took 59 millis profile ‘addChild’ took 66 millis profile ‘addChild’ took 55 millis profile ‘addChild’ took 55 millis profile ‘addChild’ took 56 millis profile ‘addChild’ took 57 millis profile ‘addChild’ took 58 millis profile ‘addChild’ took 57 millis profile ‘addChild’ took 57 millis profile ‘addChild’ took 59 millis profile ‘addChild’ took 61 millis profile ‘addChild’ took 61 millis profile ‘addChild’ took 60 millis profile ‘addChild’ took 59 millis profile ‘addChild’ took 60 millis profile ‘addChild’ took 60 millis profile ‘addChild’ took 62 millis profile ‘addChild’ took 62 millis profile ‘addChild’ took 62 millis profile ‘addChild’ took 63 millis profile ‘addChild’ took 63 millis profile ‘addChild’ took 64 millis profile ‘addChild’ took 63 millis profile ‘addChild’ took 65 millis profile ‘addChild’ took 65 millis profile ‘addChild’ took 67 millis profile ‘addChild’ took 66 millis profile ‘addChild’ took 66 millis profile ‘addChild’ took 66 millis profile ‘addChild’ took 67 millis profile ‘addChild’ took 69 millis profile ‘addChild’ took 70 millis profile ‘addChild’ took 70 millis profile ‘addChild’ took 71 millis profile ‘addChild’ took 70 millis profile ‘addChild’ took 71 millis profile ‘addChild’ took 72 millis profile ‘addChild’ took 71 millis profile ‘addChild’ took 71 millis profile ‘addChild’ took 72 millis profile ‘addChild’ took 72 millis profile ‘addChild’ took 73 millis So not only is it very slow, it gets incrementally slower with each call. The whole thing takes over 6 seconds for these 100 objects being added. 100 sounds like a lot but Ive done other projects where Ive added 1000+ objects without any major slowdown like this.
