Re: performance problem

[Brian Leung <livia74@ctimail3.com>]

hi all,
my object design like:

dn: uid=a0003,ou=dialup,o=testing
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: inetLocalMailRecipient
objectClass: radiusprofile
objectClass: posixAccount
objectClass: PureFTPdUser
cn: a0003
sn: a0003
ou: dialup
uid: a0003
uidNumber: 1001
gidNumber: 1001
homeDirectory: /home/a0003
description: PPP_UXPW
loginShell: /sbin/nologin
userPassword: tttttttttttttttttttt
FTPQuotaMBytes: 6
FTPuid: 1001
FTPStatus: enabled

And, i already add

index default eq
index uid,cn,sn

to the slapd.conf. but the performance is still bad.
