How to increase the memory heap size on IntelliJ IDEA?

Question

I want to allocate around 1GB of heap size, but I can\'t seem to figure it out.

How to do this?

Answer 1

For developers who use Ubuntu, following will help to increase heap size in InteliJ Idea. Following versions are used by myself at the moment.

• Ubuntu 16.04 LTS (64 bit)

• InteliJ IDEA 2016.3.4

Go to the location where the IDE is installed and find the following file. (In my case it as follows)

/home/abcde/Softwares/idea-IU-163.12024.16/bin

Then select the idea64.vmoptions file and edit it.

Remove default configuration and paste the below mentioned.

-Xms512m
-Xmx2024m
-XX:MaxPermSize=700m
-XX:ReservedCodeCacheSize=480m

Now restart the IDE and changes should reflect the IDE environment.

Worked for me to overcome Java heap size related issues.
