Hello, I have a problem that Kibana is taking too much RAM after upgrading to version 9.4.3

consumption in previous versions (from stack monitoring) 8.17.0 & 8.19.0 :

consumption doubled after upgrade (9.4.3):

Also, the browser became really slow and consumed more RAM than usual from one single dashboard, I used to open 4-5 concurrent dashboards to reach the 1.2GB mark :

we were running a version 8.17.0 cluster (3 ES nodes, 2 Kibana nodes, 1 logstash node & 2 fleet servers with APM integration), decided to upgrade to the latest version 9.4.3 then this happened.  
steps : 8.17.0 ==\> 8.19.0 ==\> 9.4.3

Note : --max-old-space-size is set to 2096 on both Kibana nodes, ES RAM and CPU usage is normal as previous versions

Not exactly sure about the increase of Memory on the browser, but version 9.4 requires more resources for the Kibana service, 2 GB is the minimum now I think.

On my cloud deployment I've had to increase the Kibana resources.

I will increase the maximum memory for Kibana and see how it goes, though i think the bigger issue is the browser sudden consumption increase since the upgrade. A bit of slowness when loading data is tolerable but browser lag is not 😕
