Just updating this issue. Finally all is working.
All my config was OK. After update V7000 to 7.2.0.11 version, firmware update to emulex components to version 10.3.144. VMWare Esxi 6.0 and drivers be2iscsi to version 10.4.255, the performance is normal.
By the way, after update V7000 software the iSCSI port go back MTU to 1500...so again must be changed to 9
