I tend to find the overhead of the JVM appears to contribute the most. If I have -Xmx 128MB for example, around 200MB will often be shown in Windows task manager, or whatever.
Maybe this is addressed in the talk, any my "overhead" is actually my own mis-used data space which I am not aware of.
- jfim 11y agoThe Xmx flag controls the maximum heap size. The JVM has other things that are outside of the heap (the JVM process itself, the code cache, native buffers, resource handles, etc.).
- dangravell 11y agoThat's my point, perhaps clumsily put. It's the stuff outside the heap that appears to take up much of the space.
