High cpu-usage when accessing trough Safari on MacOS Catalina #157

frepke · 2020-10-12T12:54:46Z

When accessing the webpage trough MacOS Catalina on my Macbook, the cpu usage is above 100% and the webpage freezes.
With Firefox running on the same machine there's no problem and everything works fine and smooth.

Nice project btw 👍

Hmm. My usage has been around the same for both. Would you be able to post the versions of your browsers as well as if there are any browser errors? (F12 > console tab)

frepke · 2020-10-12T14:56:29Z

My Safari version is 14.0 (15610.1.28.1.9, 15610)

There's one error in the console-tab

Hmmm. Interesting but that shouldn't lead to a huge slowdown. Do the Yacht logs say anything?

btw I installed Yacht from within OMV5

SelfhostedPro · 2020-10-12T17:09:01Z

Hmmm. Nothing there has anything to do with the charts so I'm not sure on that side of things. I'll see if there's any notes about safari in particular when it comes to charts.js

frepke · 2020-10-12T17:28:15Z

Okay, thank you

SelfhostedPro · 2020-11-04T15:39:07Z

Not seeing anything from chartjs about this. I believe it's got to do with Safari not following some kind of standard. Unfortunately there's nothing I can do as far as tweaking that goes. (I've already had all the performance settings turned on.

Unfortunately,
But it is what it is, thanks anyway.

Goodluck with this awesome project 👍

frepke · 2021-03-14T11:07:15Z

Hmmm,
On my new M1 MacBook, Yacht is running absolutely smooth in Safari.

SelfhostedPro · 2021-03-14T14:59:36Z

Nice! In the new version I changed from the charting framework to try to make things better on the dashboard that may help. Let me know how it goes!
