@ -769,6 +769,14 @@ Average unused bytes per entry
category on a per-entry basis. This is the number of unused bytes on
all pages divided by the number of entries.
Fragmentation
The percentage of pages in the table or index that are not
consecutive in the disk file. Many filesystems are optimized
for sequential file access so smaller fragmentation numbers
sometimes result in faster queries, especially for larger
database files that do not fit in the disk cache.
Maximum payload per entry
The largest payload size of any entry.
