Neffarion 486 Share Posted September 28, 2020 11 hours ago, LostVirt said: Hi, So i've noticed that even if i use "-Xmx256m -Xms256m" on Debian 9 Stretch the db3 client uses around 650-750mb of ram, but on Windows 2016 server OS or whatever it is.. it only uses 260-300mb. Is this because of Debian 9 or is there any way to get it as close as Windows ram usage? You shouldn't need to use -Xms first of all What are you using to view the ram usage on the client using debian? Link to comment Share on other sites More sharing options...
LostVirt 106 Author Share Posted September 28, 2020 According to Pandemic, the issue seems to be with AdoptOpenJDK HotSpot, and ram usage is way better with OpenJ9 if anyone was wondering aswell Link to comment Share on other sites More sharing options...

I'd manually install Oracle with whatever means necessary. I'd even compile it if i had to. Had tons of problems launching bot clients with openjdk. But 3 cheers for open source anyway.

LostVirt 106 Author Share Posted September 30, 2020 update for whoever reads this post in the future. Seems like AdoptOpenJDK 11 OpenJ9 Uses way more CPU(3x?) than normal oracle java 8 jre but solves the Ram issue.. Link to comment Share on other sites More sharing options...
