[eclipse] How to increase application heap size in Eclipse?

Some say I need to do that in Run Configurations for my application. When I open that window, could you please tell me how to set the right argument and the amount of memory? Say how to set 2GB or 1.5GB?

This question is related to eclipse jvm heap

The answer is


In the run configuration you want to customize (just click on it) open the tab Arguments and add -Xmx2048min the VM arguments section. You might want to set the -Xms as well (small heap size).


Find the Run button present on the top of the Eclipse, then select Run Configuration -> Arguments, in VM arguments section just mention the heap size you want to extend as below:

-Xmx1024m

  1. Go to Eclipse Folder
  2. Find Eclipse Icon in Eclipse Folder
  3. Right Click on it you will get option "Show Package Content"
  4. Contents folder will open on screen
  5. If you are on Mac then you'll find "MacOS"
  6. Open MacOS folder you'll find eclipse.ini file
  7. Open it in word or any file editor for edit

    ...

    -XX:MaxPermSize=256m
    
    -Xms40m
    
    -Xmx512m
    

    ...

  8. Replace -Xmx512m to -Xmx1024m

  9. Save the file and restart your Eclipse
  10. Have a Nice time :)

Open eclipse.ini

Search for -Xmx512m or maybe more size it is.

Just change it to a required size such as I changed it to -Xmx1024m


In Eclipse Folder there is eclipse.ini file. Increase size -Xms512m -Xmx1024m
