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: enter image description here

I thought it's enough. But the dialog shows from time to time, and sometimes, it's no responding that I have to shutdown it.

How should set this for IntelliJ 14? Any ideas?

Open Intellij IDE's vmoptions file

For Mac Users

Help | Edit Custom VM Options...

or

Library > Preferences > Idea<YourVersion> > idea.vmoptions

For Window (32bit) Users

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

For Window (64bit) Users

C:\Program Files (x86)\JetBrains\IntelliJ IDEA <your_version>\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.

I can't startup my IntelliJ if I set -Xmx to 2048M, my computer has 8 GB memory. – Sky Feb 27 '15 at 08:39

Under Windows it could be either of the followings, depending on which installation (x86, x64) you use: "C:\Program Files (x86)\JetBrains\IntelliJ IDEA 2016.3.4\bin\idea.exe.vmoptions" "C:\Program Files (x86)\JetBrains\IntelliJ IDEA 2016.3.4\bin\idea64.exe.vmoptions" – martoncsukas Jun 09 '17 at 13:23

for the hardware grammar police, "4GB" is `4096m` (4 * 1GB = 4 * 1024MB) – ecoe Nov 28 '15 at 15:12
Was trying to commit but failed after 20 minutes from out of memory error. Did the above and the commit was processed almost instantly. Thanks! – Brian Jan 05 '16 at 15:09
The -Xmx setting also seems to work on Linux (Mint 17.3), and solved the stupid memory popup problem. This was driving me crazy. I even switched which Java IDEA boots from (it's bundled now in Linux) to the latest and greatest JRE and it was still slow. – RyanNerd May 18 '16 at 19:12
for WebStorm you want to find the webstorm.vmoptions file located in WebStorm.app/Contents/bin/webstorm.vmoptions – ART GALLERY Jan 12 '17 at 18:51

You can set IntelliJ IDEA's memory settings and your application's memory settings in the following places:

If you still see this popup frequently even with high memory allocated, try:

File > Invalidate Caches / Restart...

Seems it worked for a little time. Then the dialog shows again. – Sky Feb 27 '15 at 15:40

It really depends on the nature of the error. One thing to try is using idea64.exe instead of idea.exe.

If this doesn't help, please contact JetBrains by filing an issue to https://youtrack.jetbrains.com/newissue and attach your log there (Help | Show log).
