Hi all,
I recently update my FreeNAS from 9.2 to 9.3. Since the upgrade, my CIFS/SMB shares have suffered a significant performance decrease.
Prior to the FreeNAS upgrade, I was able to pull 90+MB/s from my Windows and Mac systems, both write and read. Now, the best I have reached is 12MB/s.
Other than the FreeNAS upgrade, nothing else has changed on my software or hardware.
After doing some searching around the forums, inhale seen some suggestions to similar issues. The most common is dropping the “SMB” version from 3 to 2. I have tried this with no success. I have also various reboots, turning the CIFS service on/off, remapping my shares on the desktop, and rebooting my switch, router, and testing all my cable with testers just to be on the safe side.
After all the above testing, I then did some transfer tests. I tried transferring the same 4.6GB file, to ensure the source file was the same. I tried to transfer it from my Windows and Mac systems. Each transfer attempt, I watched the CPU and Memory on my FreeNAS box, and it appeared fine. I also run weekly scrubs and have SMART enabled and the HDD appear fine.
So, I am reaching out for help here. My FreeNAS specs are below.
CPU: Intel Core i7 2600k
RAM: 16GB
FreeNAS Build: FreeNAS-9.3-STABLE-201501090144
ZFS Volume: RaidZ2 55% Utilized no compression
Thanks for any help.
