Hey,
i have got an quite large knx-setup (about 1.100 channels). Everythings works more or less good. But the habpanel is very slow… reloading the page i screenshot takes about 6-7 seconds.
The complete problems seems to be the items xhr file. This takes by itself about 6-7-8 seconds… and its about 534 kb in size.
Ignore the events-file - this is the one still growing because of all ajax updates.
Any idea?! Should this be that slow?
Thanks,
Patrick
Maybe have a look at this, it seems to be similar:
it seems to be different.
If i try to load the /rest/items it also needs that 6,7,8 seconds to load. Its quite big with 1.105 items.
Openhab seems to load all channels everytime. Not only the needed channels. Thats why it takes to long…
I only see the chance to remove channels (what i really dont want to do…) to speed up. Correct?
By the way:
I ve got 2 SONOS running… and i have got the album-art as items. They take about 50% of the items-file…
Question:
Is there any kind of tag inside the .items-files to define, if an item should not be exposed to habpanel? (i guess not…).
This may would solve my issue.
I have got many items, i only need to rules (for example voltage-overload for some knx-actors)… so I could reduce it by maybe 50% …
Thanks,
Patrick
I had the same problem. An Habpanel setup with a lot of items. I fixed it by changing the way how the angular diggest process works. Details can be found here.

The problem is the openHAB core though by reading through the comments. The rest API should send 500k in under a second. I guess ineffient data structures and lookups are causing this delay.
my rest API call needs 46ms to deliver 121kb (13,77kb gzip compressed) data for 437 items. The server itself is running on a intel atom system.
Also if this takes longer it should not be a big problem, because it is only the initial request. All item events later are steamed through a websocket connection.
I am not sure why… but its a lot faster now.
I removed most of my amazon alexa / echo-Binding. I just left the “Text to Speech” lines, which are the only items I really use.
But actually I dont know why those items slow it down so much…
