I use NIS to give access to HPUX clients (A, L , N ad B class) for file systems on a NAS device running Windows 2000, across a LAN.
Some users have noted that performance is not great when using this setup. For example, if a user on a HPUX client runs
$ rm b*
in a file system which is located on the NAS, a message appears saying
$ File exists
If they run the command again, then it works.
If this same command is run on a local HPUX file system of the same size and the same number of files, it work first time. The same is true if the file system is mounted from another HPUX server.
This would tend to suggest that the NAS device is the bottleneck.
Any thoughts on this ?
Thanks in advance,
Raymond

Re: Slow Performance from NAS Device to HPUX clients
Are you running NFS or samba (CIFS/9000) ??
If you're not running samba, take a look at it:

Re: Slow Performance from NAS Device to HPUX clients
No, I am not using Samba. The NAS runs Windows 2000 with Microsoft's implementation of NFS. It exports the file systems as NFS file systems. The Unix clients can then mount them via the /etc/fstab file without any problem. It is a good solution and very seamless, apart from this performance problem. As a point of information, it has also been noticed sometimes when creating or opening tar balls.

Re: Slow Performance from NAS Device to HPUX clients
In that case, what can I do to improve performance using Microsoft 2000 ? Are there any Registry tweaks I can do, for instance ?

Re: Slow Performance from NAS Device to HPUX clients
I know that since SFU 3.0 (Service for UNIX) was released - NFS was vastly improved on Windows - but CIFS still is faster.
