Hello:

We have used glusterfs3.4 with the lasted samba-glusterfs-vfs lib to test samba performance in windows client.

two glusterfs server nodes export share with name of "gvol":
hardwares:
brick use a raid 5 logic disk with 8 * 2T SATA HDDs
10G network connection

one linux client mount the "gvol" with cmd:
[root@localhost current]# mount.cifs //192.168.100.133/gvol /mnt/vfs -o user=kane,pass=123456

then i use iozone to test the write performance in mount dir "/mnt/vfs":
[root@localhost current]# ./iozone -s 10G -r 128k -i0 -t 4
.....
File size set to 10485760 KB
Record Size 128 KB
Command line used: ./iozone -s 10G -r 128k -i0 -t 4
Output is in Kbytes/sec
Time Resolution = 0.000001 seconds.
Processor cache size set to 1024 Kbytes.
Processor cache line size set to 32 bytes.
File stride size set to 17 * record size.
Throughput test with 4 processes
Each process writes a 10485760 Kbyte file in 128 Kbyte records

Children see throughput for  4 initial writers =  487376.67 KB/sec
Parent sees throughput for  4 initial writers =  486184.67 KB/sec
Min throughput per process =  121699.91 KB/sec
Max throughput per process =  122005.73 KB/sec
Avg throughput per process =  121844.17 KB/sec
Min xfer = 10459520.00 KB

Avg throughput per process =  122854.10 KB/sec

linux client mount with cifs , write performance reach 480MB/s per client;

but when i use win7 client mount the "gvol" with cmd:
net use Z: \\192.168.100.133\gvol <smb://192.168.100.133/gvol> 123456 /user:kane

then also use iozone test in dir Z, even with write block 1Mbyte :
        File size set to 10485760 KB
        Record Size 1024 KB
        Command line used: iozone -s 10G -r 1m -i0 -t 4
        Output is in Kbytes/sec
        Time Resolution = -0.000000 seconds.
        Processor cache size set to 1024 Kbytes.
        Processor cache line size set to 32 bytes.

        Throughput test with 4 processes
        Each process writes a 10485760 Kbyte file in 1024 Kbyte records

        Min throughput per process                    =   37039.91 KB/sec

        Max throughput per process                    =   36913.29 KB/sec
        Avg throughput per process                    =   36910.53 KB/sec
        Min xfer                    = 10484736.00 KB

iozone test complete.

then reach 140MB/s

so , anyone meet with this problem.Is there win7 clinet to reconfigure to perform well?

Thanks!

Hi kane,

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 .

e.g: entry in smb.conf for one of volume "smbvol" of mine looks like below

[gluster-smbvol]
comment = For samba share of volume smbvol
vfs objects = glusterfs
glusterfs:volume = smbvol
path = /
read only = no
guest ok = yes

Kindly copy the entries in smb.conf  for your gluster volume in this email.
