It took approximately 22 hours to load our database on the Netscape servers. In addition, the servers were corrupting themselves frequently -- About once every two weeks. This meant a massive timesink to reload the servers which was a direct cost to the University in time that could have been better spent elsewhere. This decreased to 2 hours 30 minutes under OpenLDAP 2.1. Further improvements have been made since that time to the OpenLDAP bulk loading mechanism. At this point, we've migrated to Linux 2.6, expanded our data sets and indices, and it only takes approximately 20 minutes to fully load our DB. --Quanah One other improvement that Stanford achieved via moving to OpenLDAP was the massive decrease in load times.
