Slow File Attributes

I have a DS25 running Tru64 version 5.1A (patch kit 2).

I am seeing extremely slow response to an ls -F or ls -l command when run on
a directory of 569 entries (mostly regular files but there are 6
sub-directories, 2 symbolic links, and one of the files is executable). The
directory is on a V3 AdvFS file system located on an old HSZ40 RAID5 set,
but this performance is abysmal (worse than we saw when the RAID set was
attached to an AlphaServer 1200 running 4.0F). It takes at least 30 seconds
to get the response back, sometimes as long as a minute and a half! A
normal ls returns immediately with no perceptible delay.

I am stuck as to where to look for answers. My root, /usr, and /var are on
V4 file systems and do not have this problem (ls -F of a directory with
2000+ entries returns immediately)
