Date Wed, 22 Sep 2010 13:34:21 GMT

    [ https://issues.apache.org/jira/browse/DIRSERVER-1555?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12913548#action_12913548

Jean-François Melian commented on DIRSERVER-1555:
-------------------------------------------------

Some tests later :
without VM


Version 1.5.7 Windows seven: Dell OptiPlex 780 3325 Mo Ram
very slow in 32 or 64 bit (2 PC 32-bits and 1 64-bits)

Windows XP SP2: Dell OptiPlex GX280 2GO Ram
Faster On  two different PC.

With my PC (Windows Seven32 bits) the following tests don't improve performance:

IPv4 ipv6 
Stop the Windows Firewall
Stop the virus
Disabling the IP network
Test with apache DS installed as a windows service (Windows installer)


Testing version 1.5.5 and version 1.5.6:
  - Windows Seven: very slow
  - Windows XP SP3: fast

> I have generated a ldif file :  400 users and 20 groups with 100 user per group
>  - The 400 users have been imported rapidly :< 15 secondes for the 400 users   =>
0.03 second per user
>  - The 20 groups have been imported very more slowly : : > 5 minutes             
      => 15.5 seconds per group
