Dreambot Using more memory than DBLauncher specified

[falador1 2]

UPDATE: Installing new java from Open J9 helped. Some reason Oracle's and Hot's were no good.

 

Hey all,

Been working on a couple of bots and getting the memory and CPU usage as low as possible. I have a couple of questions on what the launcher says vs what Windows says its using.

When I open up the launcher and select "Maximum memory usage " and set it to 256MB

But when I open up task manager Windows says its using more.

 

I remember that I used 512MB limit before. Please help!

I think it might be an issue with Hotspot JVM and Windows
Try uninstalling your current java and install JDK 8 with OpenJ9 JVM (https://adoptopenjdk.net/?variant=openjdk8&jvmVariant=openj9)

Update/Bump

I followed these steps

Download and Installed.

 

Removed old Java and Changed the ENV variables to

for Path and JAVA_HOME

New Java version above

Removed Client.jar and redownloaded via DBLauncher.jar

(Note -- I get Outdated java warning when starting up)

 

Magic! Thanks!

If you use a profiler (something like JProfiler or VisualVM) it may mess w/ it and cause DB to be unreadable via the profilers. (Btw profilers are better at detecting actual resoruce usage since it detects it at the JVM level  )

 

Edit: Just tested it w/ latest version of AdoptOpenJDK 1.8 OpenJ9 and can confirm that VisualVM and JProfiler do NOT work with OpenJ9. I even tried to specify where the JDK is located and still didn't get it to work. Just a heads up for the people who use either profiler to measure resource usage .
