+ - "total": total amount of memory in bytes (json-int)
+ - "duplicate": number of pages filled entirely with the same
+ byte (json-int)
+ These are sent over the wire much more efficiently.
+ - "skipped": number of skipped zero pages (json-int)
+ - "normal" : number of whole pages transferred. I.e. they
+ were not sent as duplicate or xbzrle pages (json-int)

- "xbzrle-cache": only present if XBZRLE is active.
It is a json-object with the following XBZRLE information:
- - "cache-size": XBZRLE cache size
- - "bytes": total XBZRLE bytes transferred
+ - "cache-size": XBZRLE cache size in bytes
+ - "bytes": number of bytes transferred for XBZRLE compressed pages
- "pages": number of XBZRLE compressed pages
- - "cache-miss": number of cache misses
- - "overflow": number of XBZRLE overflows
+ - "cache-miss": number of XBRZRLE page cache misses
+ - "overflow": number of times XBZRLE overflows. This means
+ that the XBZRLE encoding was bigger than just sent the
+ whole page, and then we sent the whole page instead (as as
+ normal page).
