Subject [jira] Commented: (DIRSERVER-1555) LDIF import very slow
Date Thu, 23 Sep 2010 19:28:32 GMT

    [ https://issues.apache.org/jira/browse/DIRSERVER-1555?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12914180#action_12914180
] 

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

The tests have been made with standart Apache DS and studio on the same host.
3 different hosts for seven tests but with server and studio on the same host.

We have no problem with transfer speed when we copy files from one computer to another for
example.
But I asked a colleague to help me verify the network configuration of my computer.
