Any suggestions are appreciated. Khoa ----------------------------------------- Are you searching for the same entries each time? What exactly are you searching for? Are the entries that you are searching for indexed? What are the specs of the server? Is the box heavily loaded? Dan

But generally I would check the cachesize & idlcachesize setting in slapd.conf, and I would ensure I have a properly configured DB_CONFIG file if it is back-bdb or back-hdb. --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration
