Anyone interested? > A very cornerstone assumption in LDAP is reads will outweigh writes, but I didn't find any real issue with write performance anyway. The farm of FreeBSD front ends would talk to an NFS backend (like a Network Appliance) so 'where' you commit your writes would be a moot point. If you are going to use this for a password database (I think that was your use) then why do you think writes will be so significant? (just curious). Our use is for username/location,phone number,email address lookups - which I beleive is probably the most frequent use of LDAP in a commercial environment. That environment is extremely stable - very little change occurs. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
