CIFS client mounts meta ops 30 times slow than server
Hi Samba users,
We would like to use samba for re-exporting our other distributed file
system (BeeGFS). However, we found that the meta data operations are very
slow (dir stat, removal etc.). On SMB client the performance is more than
30x slow than on the SMB server. We would expect some slowness but this is
too big a drop.
This is the result on CIFS client
$ sudo mdtest -b 10 -I 10 -L -z 2

CIFS client mounts meta ops 30 times slow than server
...times on the same folder within a
short period of time. The network packet sizes are almost equal every time

Isn't there supposed to be some page cache or dentry cache that could
accelerate this, under the loose cache policy? Or is this the expected
behavior?
