to scan the entire directory looking for strcasecmp(<filname>,
<scanned-filename>). If anything matches then it will return the
<scanned-filename>. But the problem is the scan is costly. So I wonder if
this is the reason for the CPU spikes.

directory heals. But this is happening even when no self-heals are
required. So I had to move away from that theory.
These getxattrs are triggered when a SMB client performs a path based
operation. It is necessary then that some client was connected.
The last fix to go in that code for 3.6 was
http://review.gluster.org/#/c/10403/.
I am not able to determine which release of 3.6 it made into. Will update.
Also we would need version of Samba installed. Including the vfs plugin
package.
There is a for loop of strcmp involved here which does take a lot of CPU.
It should be for short bursts though and is expected and harmless.
