Usual caveats of “you should run load to see if it’s truly wasted”, but we do know that Java defaults are not ideal out of the box and so we analysed a ton of workloads on Azure and came up with this: https://learn.microsoft.com/en-us/java/jaz - better defaults out of the box for the JVM in containers at runtime.

That doc is gold thanks for linking.

Yeah defaults are the enemy here. Most of the waste I'm seeing in the data comes from generic Spring Boot apps running with out of the box settings where the JVM assumes it owns the entire node.

No source, useless outside of azure.

You can just install it outside of Azure: https://learn.microsoft.com/en-us/java/jaz/overview#install-...

Note: the tool calls out to Microsoft but the docs don't say what data is shared ("telemetry"), better make sure your firewalls are functioning before running this tool.

Not sure what the source license story is.
