Just tested and got 540+MBytes/s read bandwidth via 10GE. Without readahead =3D=3D readahead=3D1: 63 readahead=3D2: 95 readahead=3D4: 159 readahead=3D8: 280 readahead=3D16: 540 16 is the maximum: src/sys/fs/nfs/nfs.h:#define NFS_MAXRAHEAD 16 /* Max. read ahead # blocks */ But I think I can get more bandwidth if increase it. --=20 You are receiving this mail because: You are the assignee for the bug.=
