Symptoms

Oracle Virtual Directory (OVD) Server  11g.

Multiple adapters configured to talk to various backend ldap stores.

Searching through some OVD adapters are slower than a direct search through the backend, i.e., Microsoft Active Directory (MS AD) ldap servers.  

For example, running slamD test against backend ldap stores directly, getting about 1500 records per second.  Running same SlamD test through the same ldap store through OVD, it returns about 80 records a second.

Or an application logins, such as Oracle Access Manager (OAM) or a custom application, is very slow, e.g., as OVD logs show multiple searches for large number of groups the user can belong to.

Command line time ldapsearches directly to the backend LDAP server with same credentials, base dn, filter and requested attributes as seen in the OVD log, are fast, but are slow when pointing to OVD.
