[Gluster-users] Gluster 3.4 Samba VFS writes slow in Win 7 clients

[kane]

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 at 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 at 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

	Children see throughput for  4 rewriters 	=  491416.41 KB/sec
	Parent sees throughput for  4 rewriters 	=  490298.11 KB/sec
	Min throughput per process 			=  122808.87 KB/sec 
	Max throughput per process 			=  122937.74 KB/sec
	Avg throughput per process 			=  122854.10 KB/sec
	Min xfer 					= 10474880.00 KB

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 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.
        File stride size set to 17 * record size.
        Throughput test with 4 processes
        Each process writes a 10485760 Kbyte file in 1024 Kbyte records

        Children see throughput for  4 initial writers  =  148164.82 KB/sec
        Parent sees throughput for  4 initial writers   =  148015.48 KB/sec
        Min throughput per process                      =   37039.91 KB/sec
        Max throughput per process                      =   37044.45 KB/sec
        Avg throughput per process                      =   37041.21 KB/sec
        Min xfer                                        = 10484736.00 KB

        Children see throughput for  4 rewriters        =  147642.12 KB/sec
        Parent sees throughput for  4 rewriters         =  147472.16 KB/sec
        Min throughput per process                      =   36909.13 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!
