Jean-Fran=C3=A7ois Melian commented on DIRSERVER-1555:
-------------------------------------------------

java -version :
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)

I have split the ldif file in 2 parts :
 -One for users
- One for groups

I have enable DEBUG log4j.

For Groups apacheDS lost some seconds at each line like
DEBUG [org.apache.mina.filter.codec.ProtocolCodecFilter] - Processing a MES=
SAGE_RECEIVED for session 1
