samba - Oct 2014 - Performance tuning of Samba4.1 LDAP CRUD operations

Hi, I would like to accelerate CURD operation of LDAP.

Please let me know a tuning setup of OS or Samba.

Although I am performing shift verification to Samba 4.1.12 from
OpenLDAP 2.3, the CURD operation using a LDAP interface becomes 1/10
or less speed compared with OpenLDAP.

Although this OpenLDAP is performing an optimized tuning setup, Samba
is in the default state immediately after carrying out "samba-tool
domain provision".

Even if it sees "man smb.conf", there is no information about
performance tuning and I am troubled. ><

Hi, I take it that CURD = 'create, update, read, and delete' and you 
want to speed up any of these operations against samba4 AD.

You could try ldb-tools instead of the standard ldaptools, these were 
written to be used with samba4, they provide ldbsearch, ldbmodify etc
