I set up my first new Free NAS system for a lab machine. I created an iscsi share to a citrix xen server. The performance was not so great. so I wanted to check it with NFS and noticed a huge difference.
With iscsi:
dd if=/dev/zero of=/tmp/output conv=fdatasync bs=384k count=1k; rm -f /tmp/output
1024+0 records in
1024+0 records out
402653184 bytes (403 MB) copied, 121.485 s, 3.3 MB/s
With NFS:
dd if=/dev/zero of=/tmp/output conv=fdatasync bs=512k count=1k; rm -f /tmp/output
1024+0 records in
1024+0 records out
536870912 bytes (537 MB) copied, 1.22239 s, 439 MB/s
any one have any thoughts.
