Slow Read on Write Speeds on 2.5Gbe Network

[BenP511]

Hi still on trial for unraid all is great apart from transfer speeds to and from pc... which is obviously quite an issue.

Both pc and server are wired via realtek 2.5Gbe to Netgear Nighthawk SX-10.

Currently running the beta as its the only one to natively support the realtek lan

 

I would expect over 100MBs reads on the network as my previous NAS netgear Readynas 214 handled it just fine and that was 1Gbe?

 

I have attached some pictures and upload the diagnostics file, any help would be apricated before I take the plunge and buy

 

UPDATE: Reading from the Cache is Fine 200+ MBs and little cpu use, but reading from the array spikes all the cores to near full and is slow around 66MBs

Are you sure no write still flush to disks during read test ?

 

Pls check on "Main" tab for all disk status.

Yeah nothing is flushing mover not invoked, cache is empty

Thanks for the help

Samba aio was enable for -beta30, it won't be for future releases since it can cause low read speeds with some devices, see if this makes any difference:

 

-stop array

-go to Settings -> SMB

-add to SMB extras:

aio read size = 0

-start array and retest

Thank you! all sorted
