Help me understand these speeds.
Setup: Computer/FN version in sig. All 1000/100/10 network, including computers.
Speeds:
Inside the tower RAIDz to single ZFS disk via rsycn ~50 MB/s
NFS: FN to Linux ~ 60 MB/s read (~35 MB/s write)
CiFS: FN to Win7 ~80-90 MB/s
No one was more suprized than me with the samba/cifs speeds! I tinkered with samba by adding this via GUI CIFS -> Aux parameters (it was a cut and past from a site talking about samba tuning). Not sure if it is in the right spot, but these speeds are good.
log level = 1 # Default is 0
socket options = TCP_NODELAY IPTOS_LOWDELAY
read raw = yes # Default
write raw = yes # Default
oplocks = yes # Default
max xmit = 65535 # Default
dead time = 15 # Default is 0
getwd cache = yes
lpq cache = 30
When I first set up the box, I thought the max I could expect would be ~50 MB/s given the internal RAIDz to HD copy speed. Now each layer of sharing I add, I am suprized.
Questions:
How can I tune my NFS, which I thought would faster than CiFS, to match or exceed CiFS/samba? At the moment it is setup as it was out of the box.
Number of servers for NFS: currently default of 4. Does that mean the thread is split into 4 and more would mean faster transfers? Or does that mean 4 simultaneous NFS users are able to use the service?
Thanks for your thoughts!
I am going to go live today with this FN box, thanks for all your suggestions and help.
