I'm seeing some strange things happen that i can't really explain.
I'm using the XFS with SLES 9 and 2.6.5-7.97 on x86_64.
I'm filling up 6TB in one shot with 16mb files. When I delete the
directory that contains all the files and then go back the to refill
the directory again, I get performance problems.
Can you be more precise about what your performance problem is and
how you are reproducing it?
BTW, if you are using the cfq elevator, what happens if you
"echo 128 > /sys/block/sdXX/queue/nr_requests" for each block device
that makes up your filesystem?
