Lots of SVG drawing is heavy on the latest version of Safari.
Chrome, Firefox and Microsoft Edge don't have this issue.
I noticed this issue on November 1, 2022.

Live demo with steps to reproduce

Affected browser(s)
Safari 16.1(17614.2.9.1.13, 17614)

Thank you for the report! Could you please Thank you for the report! Could you please add some more details to it?

- What do you mean by "heavy"? Are you finding it to be slower than in other browsers, or something else? And if it's slow, how did you measure?

- Is this known to affect anything besides this test?

- What hardware are you using to compare?

- I noticed that rendering is slower than other browsers when viewed with safari.

- It happens when I draw a chart with a Highcharts (https://www.highcharts.com/). I contacted Highcharts, but was told that it was a Safari bug (https://github.com/highcharts/highcharts/issues/18089) .

- I used MacBookPro. MacOS version is 12.6.1.
