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!
kane
