samba - Dec 2012 - vfs_commit question.

Hello,

I am looking to check out the performance impact of vfs commit for different
threshold values.  I downloaded samba3.6 for RHEL6
(http://www.enterprisesamba.org/samba-packages/red-hats-rhel/rhel-6/) and added
the following settings in the smb.conf:


*         vfs objects = commit

*         commit:dthresh = 4K

Irrespective of dthresh value (4K, 64K, 512K) I don't see any performance
impact.  I was expecting smaller dthresh value to cause negative performance
impact.

I increased the samba logging to level 10 but other than successfully able to
load vfs commit module I don't see any log message showing the dthresh
value.  I grabbed for 'thresh', 'sync', 'flush'.

I appreciate your help.  Let me know if you have questions.

Thanks,
Dharmesh Patel
