It's really 64 MB, of which 32.5 MB is available for allocation. The 8 MB is the initial amount available for allocation. (If this sounds unnecessarily complicated, that's only because it is, with emphasis on the unnecessarily.) > I'd love some help interpreting the heap info I see above. Anything in particular? The Heap Configuration values are those in play at JVM startup; the Heap Usage values reflect the state of the heap when the snapshot was taken. If not prohibited, the GC code will adjust the sizes of the eden, from/to, and tenured spaces dynamically as conditions change.
