How to give more memory to IntelliJ Idea 9-11

Question

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 s

Answer 1

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
