High CPU-Usage on Snapshot #1597

  • Platform information:
    • Hardware:Intel® Celeron® CPU J1900 @ 1.99GHz/8 GB RAM/256 MB SSD
    • OS: Debian GNU/Linux 9
    • Java Runtime Environment: openjdk version “1.8.0_212”

With the snapshot before i had a CPU usage around 5%
binding = systeminfo,serial1,astro,squeezebox,homematic,http1,exec,ntp,network,avmfritz,fritzboxtr0641,amazonechocontrol,neeo,tradfri,modbus

After updating to #1597 CPU went up to about 30% - OH was nearly useless, rules delayed for about 5 Minutes.

Uninstalling the binding “modbus” brought CPU down to about 10% what is still to high, but OH is running in real-time again.

Thank you for helping… regards Tom

With Snapshot #1601 the modbus binding and everything else is working again in real-time…

…but CPU-Usage is still around 30%
