only does the data need to be stored but also the overhead information for keeping track of where the data
is located on the storage media. This overhead is called the “metadata” It consists of the directory
information, the space allocation and any other data associated with a file that is not part of the data
contained in the file. It is normal for the initial write performance to be lower than the performance of re-
writing a file due to this overhead information.

Hi kane,<br>
<br>
I do run IOs using win7 client with glusterfs3.4 , but I never
compared the performance with Linux cifs mount. I don't think we
need to do any special configuration on Windows side. I hope your
Linux and Windows client have similar configuration i.e. RAM, cache,
disk type etc. However I am curious to know if your setup uses the
vfs plug-in correctly. We can confirm that looking at smb.conf entry
for the gluster volume which should have been created by "gluster
start command" automatically .<br>
<br>
e.g: entry in smb.conf for one of volume "smbvol" of mine looks like
below<br>
<br>
[gluster-smbvol]<br>
comment = For samba share of volume smbvol<br>
vfs objects = glusterfs<br>
glusterfs:volume = smbvol<br>
path = /<br>
read only = no<br>
guest ok = yes<br>
<br>
Kindly copy the entries in smb.conf for your gluster volume in this
email.<br>
