How to change heap size

In version 6.0.1 for Linux, I notice the readme file says that to change the heap size, one should edit idea.sh and:

4. To adjust the value of JVM heap size open idea.sh and
modify the JVM_ARGS variable (-Xms and -Xmx).

However, there is no reference to the variable JVM_ARGS in idea.sh. Has this functionality been moved somewhere else?

You should edit the idea.vmoptions file. We'll correct the readme file.

Thanks much! I thought it would be something like that (or a run time parm).

For small project sizes, and 2 gig of memory, do you have a suggestion of what settings to use?

256M should be generally OK. Increasing the heap size too much is not always
a good idea because it will lead to longer GC pauses.
