Current Entry Cache Size (in Entries) The total number of directory entries currently

Table 13.8. Summary Information
Performance Metric Current Total
Hits The number of times the database cache
successfully supplied a requested page. A
page is a buffer of the size 2K.
Tries The number of times the database cache was
asked for a page.
Hit Ratio
The ratio of database cache hits to database
cache tries. The closer this value is to 100%,
the better. Whenever a directory operation
attempts to find a portion of the database that
is not present in the database cache, the
directory has to perform a disk access to
obtain the appropriate database page. Thus,
as this ratio drops towards zero, the number
of disk accesses increases, and directory
performance drops.
To improve this ratio, increase the amount of
data that the directory maintains in the
database cache by increasing the value of the
Maximum Cache Size setting. See Section 2,
“Tuning Database Performance” for
information on changing this value using the
Directory Server Console.
Pages Read In The number of pages read from disk into the
database cache.
