6.9.2 > 4nic LAG transfers > abysmal performance

Featured Replies

Hey all, new user here.

 

I have a Synology NAS that has a 4nic LAG plugged into my Unifi switch. The new Dell R510 also with a 4 nic LAG also plugged into the same switch.

 

My transfers are running at around 23-30 MB/s (approx 230mbps). Which to me seems terrible being that there is theoretically 4000mbps (500MBps) to play with.

 

I am transferring into a 2 disk SSD cache (250GB each).

 

I have set the disk Tunable (md_write_method): to 'reconstruct write' as it was mentioned in another post regarding performance.

 

Any suggestions on next steps?

 

PS. I am currently still in trial mode. Could this be a limitation of being in trial still?

Since the mover is now moving content from the cache, transfers have dropped to 10MB/s.

 

It got worse.......

So I slightly misunderstood LAG's.

 

What I am looking for is actually SMB3 multichannel.

 

Synology WAS supposed to be releasing that with DSM 7.1. Doesn't look like it's been added as I couldn't find any setting anywhere.

 

Can SMB multichannel be enabled in Unraid? Eventually DSM will have it added and then I should see a significant increase in performance.

 

That being said, I still thing the transfer rates I am seeing are significantly slower then they should be. Transferring a file from WIN10 to the Synology routinely hits around 130MB a sec. That's not happening here from Synology to Unraid.

Remark: the upcoming Unraid version 6.10-rc5 has a new setting to enable or disable SMB multi-channel (it is disabled by default).
