In fact, the compression ratio is higher when same_pages is taken into account:
```
orig_data_size uncompressed size of data stored in this disk.
This excludes same-element-filled pages (same_pages) since
*no memory is allocated for them*.
same_pages the number of same element filled pages written to this disk.
*No memory is allocated for such pages*.

Check `SwapTotal - SwapFree` instead of DATA if you want to check real compression ratio.
Good to know! Thanks!
