Hi All
I need to solve why this is so slow, its absolutely killing my whole system. Its unusable slow.
Its slow on my gigabit/10gbit lan with Ubiqiti wifi, its slow via 4G.
BasicUI is just fine. Doesnt matter what browser or what device I use, they are all slow. OH2 is sitting at about 5% CPU and runs on a Xeon processor with Hardware raid and SAS disks so it’s not the hardware.
Is anyone able to help me pinpoint the issue? It’s so bad, I can barely even change dashboards in HabPanel
Thank you

Also try this to verify your items requests isn’t taking too long for some reason, this would explain the delay when switching dashboards:
Correct.
If by tabs you mean dashboards, no only the visible widgets are rendered.
To debug performance problems, open the developer tools in Chrome, go to the Network tab and refresh the page. Check the Waterfall column.
If there’s a request, for instance “items”, taking a long time to complete (i.e. a long bar, disregard “events” because it’s a long-running SSE connection as explained above), that might be the cause of your dashboard taking a long time to appear.

Hi Vincent, its been fairly slow for as long as I can recall (I’ve made some posts in the past) but now its just terrible.
I’ve added a few items to existing dashboards.
@ysc , OK I shall.

Managed to fix a few issues, missing icons or scripts etc. They are now present and the pages load without error, mostly.
Theres still this one:
And also the 7seconds for items

Fixed the issue! at least with speed!
Hi All
Ive just found this post, and I have the exact same issue.
Thanks zolakk for posting, I commented out those items and my REST items speed reduced from 7seconds to 139ms.
The HabPanel dashboard is incredibly snappy now!!!
This definitely needs looking at.
Hopefully Yannick can reply on those script errors @ysc

sprintf errors are likely caused by widget trying to format states of items that happen to be non-numeric at that time (i.e. NULL or UNDEF or others). They are pretty benign.
You can prevent the CSP violation error by only using server-relative URLs when including external files (like /layout/weather/example.css), provided they are on the same origin (scheme-host-port) as HABPanel.

Ive absolutely no idea what that means
How do I change them to server relative URLs as I thought thats what Ive already got (given they are local)
