https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267631 Vladimir Druzenko <vvd@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |vvd@FreeBSD.org --- Comment #2 from Vladimir Druzenko <vvd@FreeBSD.org> --- Try mount_nfs -o readahead=16. Just tested and got 540+MBytes/s read bandwidth via 10GE. Without readahead == readahead=1: 63 readahead=2: 95 readahead=4: 159 readahead=8: 280 readahead=16: 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. -- You are receiving this mail because: You are the assignee for the bug.help
