Comparing memory snapshots
This feature lets you compare any two memory snapshots.
To compare snapshots:
- Open both snapshots.
- Select one of them.
- Use File | Compare Snapshot with... (also available from the popup menu) and select the snapshot to compare with.
The Comparison tab with memory views Classes and Classes and packages will open. The views have 2 columns: Objects (+/-) and Size (+/-). These display the differences in object counts and sizes. Positive values mean that Snapshot 2 (the later memory state) has more objects and/or its objects have the bigger total size.
100% of size corresponds to the total size of all objects in the old snapshot. Likewise, 100% of count corresponds to the object count in the old snapshot.
