Charting & tooltip in canvas mode results into performance issue

[Evan]

Using Charting with Tooltip & Magnify in canvas mode will cause significant performance regression in 1.9.1

The attached test case created 3 Series with total 150 anchor tooltips, running this in canvas mode will result into a significant performance issue e.g. make FF V.22 frozen.

This issue doesn't happen when running in svg mode, neither happened in 1.8.1 where in canvas mode there is some latency when hovering the anchor compared with svg(guess due to position calculation), but overall it's still running well.

Evan, have you tried to set canvasWithEvents:false to see if the problem is not coming from the canvas event implementation instead of charting. Charting does not need it so you can disable it and maybe this is the cause of the problem.
