increases, and directory search performance
drops. To improve this ratio, increase the
number of entries that the directory maintains
in the entry cache by increasing the value of

See Section 2, “Tuning Database
Performance” for information on changing this
value using the Directory Server Console.
currententrycachesize The total size of directory entries currently
present in the entry cache.
maxentrycachesize The maximum number of directory entries that
can be maintained in the entry cache. This
value is managed by the Maximum Entries

Database Performance” for information on
changing this value using the Directory Server
Console.
dbchehits The number of times the server could process
a request by obtaining data from the cache
rather than by going to the disk.
dbcachetries The total number of requests performed on
the directory since server startup.
dbcachehitratio The ratio of cache tries to successful cache
hits. The closer this number is to 100%, the

cache.
dbcachepageout The number of pages written from the cache
back to disk.
dbcacheroevict The number of read-only pages discarded

written to disk, possibly affecting server
performance. The lower the number of page
evicts the better.
dbcacherwevict The number of read-write pages discarded
from the cache to make room for new pages.
This value differs from Pages Written Out in
that these are discarded read-write pages that
have not been modified. Pages discarded
from the cache have to be written to disk,
possibly affecting server performance. The
