How to limit total memory consumed by Java 8 application?

Question

In order to limit total memory consumed by Java 7 application I could use the following formula (taken from this article):

Max memory = [-Xmx] + [-XX:MaxPermSize] + number_of_threads * [-Xss]

How this formula changes for Java 8 application, after PermGen has been removed?

Should I use option "-XX:MaxMetaspaceSize" to limit the maximum memory consumed by metaspace instead?

Answer 1

Yes, there is -XX:MaxMetaspaceSize instead of -XX:MaxPermSize.

Consider also -XX:MaxDirectMemorySize to limit memory for direct ByteBuffers.
