ls -Xmx memory limit for Intellij IDEA shared between open project windows?

Question

Intellij IDEA memory settings may be customized by editing -Xmx option at idea64.vmoptions. Let's say, I set

-Xmx2g

and then open 5 different projects at the same time. Can IDEA eventually consume up to ~10gb of memory, or it will be limited to 2gb+some overhead?

At memory usage monitor in the lower right corner of IDEA window, I see the different value of allocated memory for each project. On the other hand, these values seem to correlate over time.

Answer 1

It's the same single process running in the same JVM, so the limit is for all the windows/projects.
