Under heavy client load, the log shows many "deferring operation: binding" messages in the same second. slapd is using only 400% cpu (of 1600 possible).
Probably you could increase # of listeners. In a pure Bind-only workload slapd ought to be able to utilize 100% of all cores.
Do you mean the tcp port listeners on the slapd process? Do you think I'm hitting a socket accept queue max backlog or something else?
slapd -h ldap://:389 ldaps://:636
Read the slapd.conf(5) or slapd-config(5) man page section on listener threads.
