Gantt.parse method slows down the browser

#1

Hello everyone, there is a problem when I initialize my gantt diagram. Gantt.parse method slows down the browser. I use most of the suggestions for optimization on this page: Performance: Ways to Increase Gantt Docs

Gantt.parse takes a long time to complete when about 40-50 tasks are passed to it.

I also made a test by logging all handlers and this is what I got: there is a big delay between onBeforeTaskDisplay and onBeforeDataRender when gantt.parse.

Please add your configuration to the following snippet and make sure that the issue is reproduced there:

Then, click on the Save button and send me the link.
Or send me a ready demo with all the necessary JavaScript and CSS files so that I can reproduce the issue locally.
