Slow samba speed after upgrade

[SMart0711]

Hey Guys,

I've been using FreeNAS 9.10 on my small NAS Server for half a year without a problem. After upgrading to corral I noticed reduced network spped on my samba shares. Befre it was about 80MB/s /100MB/s write/read over GbE from my Windows 10 PC. After upgrading, the speed dropped to 60/80. For several reasons I switched back to 9.10 (using an older grub entry), expecting to returning to higher transfer speed. But instead the speed dropped again to 20/50. So far I tried replacing cables, switch and another PC with Win 7, but no luck. The internal speed of the ZFS Volume ( dd if=/dev/zero of=/mnt/DATA/testfile bs=500M count=3) showed about 300MB/s speed. I tried tuning samba:

Code:

ea support = no
store dos attributes = no
map archive = no
map hidden = no
map readonly = no
map system = no

...but no difference.
Do you have any idea what could be wrong?
My hardware config is:
CPU: Intel Celeron N3150
RAM: 1x 8GB • PC3L-12800S
HDD: Seagate NAS HDD 4TB, SATA 6Gb/s (ST4000VN000)

I hope someone can help me.
best regards
Sebastian

After upgrading to corral I noticed reduced network spped on my samba shares.

Downgrade back to 9.10 and wait for 11. Corral got discontinued and any issue won't be addressed.

As I wrote, already downgraded to 9.10. But the issue is still there and even got worse. Should I do a clean reinstallation? How would I do this without losing my ZFS Volume?

Ah, good.

If you have not backed up your data, do so before
proceeding.
Your Pool(volume) is not part of the OS! You can perform a fresh install and the drives that form your pool will not be affected. Once the fresh install is completed, you may need to import your
Pool to access your data. Please consult the documentation for more details

 

[SMart0711]

So, there is no way to repair this without a clean install?

Sounds like FreeNAS 11 should restore the performance you had before.

Test your network speeds using iperf. Make sure to test with the server being freenas and your Windows host.

The only way that Corral would be faster would be thanks to an improved driver. That driver would also be in FreeNAS 11.

Intel has been improving their FreeBSD drivers lately. 1st gen. 10GbE went from 7ishGb/s to 9ishGb/s in about a year.
