Contents/Info.plist

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

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

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

Answer 4

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

Answer 5

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

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
