I understand that a df, or ls -l that requires statting files should be

My guess is that you have lots of small writes before the "ls" that
generates the disk flushing. Could you pass your kernel and gfs versions
? Mind running oprofile on your node (I can pass the instructions if you
like) so I can take a look ?
