Hi Paul,
You were right: I turned off SMB, NMB & Winbind and ls -al on the
large array become fast as usual. Digging a little deeper, i found that
some of the sub-directories in /home/data had been restored from another
server and that they showed in unknown group "10432" in ls -al . So i
just did:
[root@radium home]# chgrp -R "domain users" /home/data
So in conclusion, it seems that my "ls -al" on the filesystem
containing unknown GID translated into queries to Active Directory and
for whatever reason, resulted in a delay of several seconds (like 10-15
seconds).
Thanks Paul again.
