Performance regression from dev.7 to dev.14 on iPad 3 #93

Closed jonathanolson closed 8 years ago

jonathanolson commented 9 years ago

dev.7 was acceptable on iPad 3. Will need to determine where the regression occurred.

jonathanolson commented 9 years ago

dev.10 to dev.11 was a minor regression, much worse in dev.12.

jonathanolson commented 9 years ago

Likely dev.10-dev.11 regression was reverting toImage on the oscillator. Likely dev.11-dev.12 regression is from the SVG image repaint cost.

@aaronsamuel137 & I also saw some performance degradation on iPad3 when looking at converting the color vision head image from PNG to SVG.
