I have the same program (same binary) running in different modes. From<br>GC stats I see they&#39;re using the same amount of heap now (209m) and<br>the stack is small. But in top&#39;s RES column, I see one is using 270m<br>
memory and the other one is using 622m. Forcing heap compaction does<br>not change the numbers.<br><br>I don&#39;t quite understand this difference. A program&#39;s memory usage<br>should be code, static data, heap and stack. For the same binary, code<br>
and static data segment should be the same, and now that GC stats<br>tells me heap and stack are the same, why there is a 352m difference<br>in memory usage?<br><br>Thanks<br>
