Peculiar problem, haven't the slightest idea where to start. Need advice!
RHEL5.4 box with an NFS mount point to a NAS storage device into a NAS
device with jumbo frames disabled. NAS has a samba share capability.
Users are convinced it's too slow.
At least one user is convinced that if he uses smbclient to untar the same
tarball, it takes, 2 maybe 3 minutes.
(My manual untar attempt of the same tarball has been running for 25
minutes and climbing.)
NAS is in a one-volume raid 6 - seven drives. Users not showing much
interest in splitting it into multiple volumes.
Network guys are convinced the slowness is because it's behind a 1GB router;
Not seeing anything that really worries me in /var/log/messages
Not seeing any unusual processes in top
memory use isn't excessive - not swapping
network mtu is at 1500 - wouldn't matter, since our switch ports are at
1500 anyway,
My own search attempts coming up dry. Just vaguely related academic
material that doesn't even give me a good idea where to start!
I approach the oracle!
Mike
