LDAP performance question

Hello
 
  I have setup LDAP to authenticate using pam.
but I am seeing performance lack.
I have created single ou=ykf and all user info is in there i-e uid, gid looking at slapd.log It seems slapd is looking at ou repeatedly for some reason.
I have also enabled caching
 
Here is slapd.conf
 
database        ldbm
cachesize       500
dbcachesize     200000
index   objectClass,uid,uidNumber,gidNumber,memberUid   eq
index   cn,mail,surname,givenname                       eq,subinitial
password-hash   {crypt}
password-crypt-salt-format      "$1$%.8s"
#loglevel 128
Of course all other things are in slapd.conf,
 
Here is slapd.log
You will see a user login session starts and ends, but so many time slapd is repeating I am not sure if this is default and I am not loggin anyhting
