How should I set the memory for IntelliJ 14?

Question

I just upgraded my IntelliJ to 14.0.3. But there\'s always a Out Of Memory dialog popped up to ask me to set the memory.

Following is my settings:

Answer 1

Open Intellij IDE's vmoptions file

For Mac Users

Help | Edit Custom VM Options...

or

Library > Preferences > Idea > idea.vmoptions

For Window (32bit) Users

C:\Program Files (x86)\JetBrains\IntelliJ IDEA \bin\idea.exe.vmoptions

For Window (64bit) Users

C:\Program Files (x86)\JetBrains\IntelliJ IDEA \bin\idea64.exe.vmoptions

and setup it's memory as you wish. Below is sample settings for 2GB

-Xms128m
-Xmx2048m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=240m
-XX:+UseCodeCacheFlushing
-XX:+UseCompressedOops

Hopefully this help.
