...performance is very different. The samba server has 4 1Gbps NICs and bond with mode 6, backend storage is raid0 with 12 SAS disks. A LUN is created over all disks, make as EXT4 file system, and used as glusterfs brick. On the samba server, use dd test local ext4 and glusterfs, write bandwidth are 477MB/s and 357MB/s, details as follow. When mount cifs on Centos 6.0, write bandwidth downgrade to 184MB/s and 117MB/s, very different. Using 4 win7 clients to test with SANergy/Iometer, cifs over ext4 aggregate throughput can get about 391 MB/s. However, cifs over glusterfs aggregate throughput only ca...
