How to give more memory to IntelliJ Idea 9-11

Memory ManagementIntellij IdeaJvm Arguments

Memory Management Problem Overview

This concerns Intellij from 9 to 11. In the IDEA window On the bottom right corner I see the current memory usage, typically "224M of 254M" How do I give more memory to Idea so it may read like "224M of 512M" ?

Thank you.

Solution 1 - Memory Management

On Mac, $IDEA_HOME/Contents/Info.plist

 ~: grep --context=5 Xmx /Applications/Maia-IU-94.426.app/Contents/Info.plist 
			<string>true</string>
			<key>apple.awt.fullscreencapturealldisplays</key>
			<string>false</string>
		</dict>
		<key>VMOptions</key>
		<string>-Xms128m -Xmx912m -Dfile.encoding=UTF-8 -XX:MaxPermSize=250m -ea -agentlib:yjpagent=disablej2ee,disablecounts,disablealloc,sessionname=IntelliJIdea90 -Xbootclasspath/a:../lib/boot.jar</string>
		<key>WorkingDirectory</key>
		<string>$APP_PACKAGE/bin</string>
	</dict>
</dict>
</plist>

On Windows/Linux, %IDEA_HOME%\bin\idea.vmoptions

Solution 2 - Memory Management

Edit the following file:

idea/bin/idea.vmoptions

Solution 3 - Memory Management

For Windows, in your IntelliJ Idea folder modify idea.exe.vmoptions.

See http://blogs.jetbrains.com/idea/2006/04/configuring-intellij-idea-vm-options/

Solution 4 - Memory Management

If you are using:

  • Ubuntu
  • 64 bit hardware

then you need to create idea64.vmoptions by simply copying the options from idea.vmoptions file

cat idea.vmoptions > idea64.vmoptions

The parameters remain the same: -Xmx1024M -Xms512M

Solution 5 - Memory Management

On the MacOS find the folder where Idea is installed. then open file

Contents/Info.plist

Go all the way to the bottom and find the section that looks like this:

<key>VMOptions</key> <string>-Xms64m -Xmx512m -XX:MaxPermSize=128m -Xbootclasspath/p:

Solution 6 - Memory Management

go to that path "C:\Program Files (x86)\JetBrains\IntelliJ IDEA 12.1.4\bin\idea.exe.vmoptions" and change size to -Xmx512m

-Xms128m
-Xmx512m
-XX:MaxPermSize=250m
-XX:ReservedCodeCacheSize=64m
-XX:+UseCodeCacheFlushing
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true

hope its will work

Solution 7 - Memory Management

On windows 7 (64-bits).

In the folder : C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 13.0\bin

There is a file named : idea64.exe.vmoptions

-Xms128m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-XX:+UseCodeCacheFlushing
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50

Beware that if the underlying JVM used is 32-bits, the maximum memory is still somewhere below 2048Mb
