When exporting a database that contains millions of entries via the 'export-ldif' command, the export may take hours to complete.  In the following example, it takes one hour to export roughly 37 million entries...

3,600 Seconds = 60 Minutes

[dsuser@idsync1 bin]$ ls -lah /home/dsuser/Oracle/Middleware/*

[dsuser@idsync1 bin]$

Can the export time possibly be improved?
