Thanks for the memory: Understanding the memory usage in the JVM in Windows and Linux

I’m nothing special, in fact I’m a bit of a bore
If I tell a joke, you’ve probably heard it before
But I have a talent, a wonderful thing
cause everyone listens when I start to sing
I’m so grateful and proud
All I want is to sing it out loud

Sooo I sang, thank-you for the memory tuning options for the JVM Andrew Hall, you’ve made my day. Andrew has written an excellent article detailing the inner workings of the JVM and how it manages memory, it goes quite deep starting with Kernel vs User Space, how the JVM uses native memory (including some examples to show running out of native memory), how to detect/measure heap usage and finally how to move over to the 64bit world with some caveats (native 64bit binaries for JNI libs etc).

Well worth the read.
