I test the iSER & iscsi performance in stgt.The following is the result. I test all the thing usr dd command.First,I test a partition of the system disk;then i use it as the backing-store for a lun in stgt.Stgt is compiled with ISCSI=1 ISCSI_RDMA=1 flags.I use open-iscsi on another machine for read/write with iSER protocol.The connection between the server and client is IB,details:InfiniBand: Mellanox Technologies MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE]. read: read the partition directly 105 MB/s ,iSER 50.8MB/s write:write the partition directly 103MB/s, iSER 56.5MB/s then i create a RAID0 array with 12 SATA disks for test. read:read the RAID0 array directly 869MB/s, iSER 328MB/s write:write the RAID0 array directly 815/s, iSER 195MB/s Are the results as nomarl? The performance degrades half,for the raid0 iSER write only a quarter. Could someone tell me the reason?
