Indexing
Maintaining the correct indexes is imperitive for good performance.
Always maintain an equality index on the objectclass attribute.
Always include an objectclass equality comparison in all queries.
Periodically run the slapindex utility to ensure that your indexes are
complete and consistent.
On substring comparison try to include at least three characters.
If only one or two characters are provided some versions of
OpenLDAP will not be able to statistically optimize the query
The dbcachesize directive controls the amount of memory allocated for
each index file.
Increasing this paramter can provide a significant improvement in
performance, escpecially on index rebuilds and attribute
modificaitons.
