I face a dramatic reduction of performance (factor 5-20) with migration from oh3.4 to oh4.0 on my RaspberryPI 2B.
latest DietPi: Debian GNU/Linux 11 (bullseye)
OpenJDK Runtime Environment Zulu17.42+19-CA (build 17.0.7+7)
One core is very often at 100% full load.
Many communication errors in this case with web browser.
RAM is used only by 60%,
Following Blockly took less then 3 seconds on OH3.4
Now, with oh4.0 it is running more then 90sec!
Used addons: mqtt, java-automation, jdbc maria, http, jsonpath, androidtv,
Logfile is proper - no warnings , no errors.
About 100 items.
Has somebody made similar epxerience?
I carefully read all performance forum topics but I basically do not hear any so heavy problems.
