Network speed of 10Gb is fast and reliable.
Network speed of 10Gb is fast and reliable.
We have a 10Gb network between a NAS and workstations within a Windows domain. Files transfer appears slow, similar to 1Gb connections. Average copying speed is around 30Mb/s for files moving from the NAS to a workstation. Some large files reach up to 25GB. There are two 10Gb cards connected via a 10Gb switch using LACP. A separate Cat6a cable is attached from each switch port to individual workstations, each with its own 10Gb card. These cards are likely WD SATA 6Gb/s HDDs operating in RAID6. The workstations are equipped with SSDs.
Gigabit links can deliver up to 125 MB/s, but 30 MB/s is quite slow. Have you tested without bonding? That might be causing the issue. What about FTP or other protocols? Could using several connections boost your speed beyond 1 Gbps?
I meant 130 MB/s, but I didn’t include bonding since it was the same. FTP works much slower without it. Attached are the iperf results over the 10Gb connection between the workstation and NAS. The first file is from the NAS, the second from the workstation.
I'm curious about whether you installed the 10Gb cards yourself. Could you let me know the age of your NAS? It might be that the CPU is intentionally limited for 10Gbit speeds. Would you like me to check the CPU activity during file transfers?
They included them during the NAS implementation in 2017. The CPU increases by roughly 10% while copying data.
It indicates the issue isn't related to storage. The problem began spreading at some point. Was this an updated setup or did it simply cease functioning properly one night?
We just relocated, but everything remains unchanged. No adjustments made to the switches or NAS.
