[SOLVED] Increasing RAM for Openhab

[stefan.hoehn (Stefan Höhn)]

I am bit suprised about your settings. If you look at the following thread

What -Xms (and -Xmx) options do you use?

It’s quite simple: Start with the defaults and increase gradually if you encounter lags in rules execution. If you do not, stay with your settings. For openHABian Xms/Xmx defaults are 250/350 which is fine for a 1GB ARM system and on x86 or ARM boxes with more mem probably not more harmful than the defaults. If you run on 64bit x86 you need more as code and data are usually 4 times larger. But I don’t use x86 so I cannot and won’t recommend anything there. To increase beyond what’s needed re…

you’ll see that the default settings are higher. You can change those in

/etc/default/openhab

i.e. the default should be like this

EXTRA_JAVA_OPTS=“-Xms250m -Xmx350m”
