Threading of LDAP Connections

Q.
The Novell NDS/eDirectory sizing guide for Solaris indicates that LDAP connections for eDirectory 8.5 are single threaded. Is this still true?

A.
Dear Unix Ugandy: You are mixing apples with oranges here. Let me explain. The statement in the documentation means that only one thread listens on a socket and that the TCP stack could become a bottleneck in large configurations. You need to look out for 'ListenDrop' in the network stack to detect any stack bottlenecks. Outside of this context, this statement is misleading because there is no point in having multiple threads listen on a socket. Only one of them can respond to this event and accept (establish a connection).
Since the first implementation, the actual servicing of incoming requests is handled by a pool of threads. Otherwise, we couldn't service multiple concurrent LDAP connections.
