We should provide the following information to the gecko profiler: Objects marked/swept each GC event: use to calculate mark/sweep rate. Heap size / used size. AllocKind stats & fragmentation stats. We should also provide allocation rates during mutator time, and seperate this by AllocKind and where the allocation is placed (nursery, always tentured, pretenured). If the profiler can compare profiles based on some of this info we can easilly quantify the benifits due to changes we make to the GC.
