I've been trying to figure out why my read performance over LAN degraded after installing FreeNas 9.1
My server is dedicated to Freenas, nothing else is running (no jails). There's really only one device accessing the Freenas server as well. I've tried both onboard NIC ports. Here's the specification of the server
Processor: Intel i3-3220
Motherboard: Intel S1200KPR
Memory: 16GB ECC DDR3-1600
Zpool: Raid1 with 2x2TB
The only tuning I've done is enabling autotune. My write performance over LAN from PC to FreeNas is about 80-100MB/s+. That did not change from going from 8.3 to 9.1.
My read performance over LAN from Freenas to PC went from 80-90MB/s down to 20-30MB/s going from 8.3 to 9.1. I'm using a 3GB ISO image and copying to a SSD drive.
I am almost certain this nothing to do with CIFS as I did a test using FTP and got similar performance.
Here's the autotuned generated settings:
kern.ipc.maxsockbuf 2097152
net.inet.tcp.recvbuf_max 2097152
net.inet.tcp.sendbuf_max 2097152
vfs.zfs.arc_max 10539046102
vm.kmem_size 11710051225
vm.kmem_size_max 14637564032
Any suggestion would be helpful. I can't go back to 8.3 as I've updated the Zpool (oops) :(
