Greetings,
I am seeing EXTREMELY poor performance backing up a filesystem located on a
NT server. Here are the details:

NT Server 4.0( ADSM server and client...different boxes)
ADSM Server 3.1.2.0
ADSM client 3.1.0.6
Clarion Hardware RAID5
175 GB filesystem
600,000+ files (and growing rapidly)
NT cluster

There are 4 RAID5 filesystems on the same hardware and we are seeing the
poor performance on ONLY one of the filesystems.
The other filesystems are not as large and also do not have nearly as many
files. The performance on the filesystem in question is over 20 times
slower than the other filesystems. Additionally when we use NT explorer to
display the files and directories, it takes about 6-7 seconds to display
the directory tree and an additional 6-7 seconds when scrolling through the
tree. We do NOT see this degredation when issuing the "dir" command.
To try and isolate the problem, I ran a selective backup using the trace
option with the "fileops" flag. I ran this on both the poor performance
drive and a drive that is performing well. Below is part of the results for
the filesystem performing poorly. Where the trace output shows nearly a
half a second in the "ntfileio.c" section PER FILE and over a second
between "psfsinfo.c" and "ntfileio.c" PER FILE. On the other filesystem
there is NO elapsed time for these processes.

Has anyone experienced anything like this? Any suggestions?
