The by far greatest advantage is on Intranet-systems that are using NIS. Try an ls /home/ on a NIS system with and without nscd (several times, first time is the same of course). Looking up UIDs/GIDs via a network service - most often NIS(+) but also things like LDAP - takes a lot of time and network traffic, which nscd saves. On our SuSE internal workstations we definitely don't want to miss nscd! It matters less for your standalone home-pc.
I work every day on a system where my /home directory is NFS mounted on a large lan. We use NIS. I probably do ls -l man many times a day. If it making a difference to you, then I would suggest that the implementation of NIS for Linux is somehow not quite up to that used on Sun Solaris ?? Well, could be true. Obviously if you notice a difference then it does have a use ! Et Fin Cliff
