I do have an application server (with a database) on a nss filesystem.
Users do access the filesystem, but there are not special rights
required. Therefore not really a need for NSS.
I wonder whether I should not migrate our current OES Application Server
to non NSS volumes.I do have performance issues and think it might be
better afterwards.

1) Do you have any performance experiences (NSS towards others)?
2) Without NSS do I still have to use EVMS and is it also recommended to
use two RAID subsystems?
3) Are there any other problems I might have using a non NSS filesystem?
4) Is in this is case a native Linux Volume considered as "best practice" ??
