As the password file grows larger, it will take longer for people
(especially at the bottom of the file) to login. This is the case for any
UNIX system. I would think that it would take longer with a shadow
password file, since the login authentication now has to search through
both passwd files.
I haven't had a need for it, but you use to be able to set a bit on the
file's permissions that forced it to stay in RAM. This was several years
ago and was not Linux. I'm not sure if there is an equivalent ability in
Linux though. This would greatly improve the authentication speed for a
large password database, if you could do it.
