NFS performance

Recommended Posts

Hi,

 

I have a Xpenology with DSM 5.2 on a Proxmox server. I have set up different nfs share and everything is close to be perfect. The only problem I have is the NFS performance.

 

When the Xpenology starts, I have very good performance with NFS (100MB/s) but it decreased over time until falling to a pitiful (1MB/s)...

I tried to change nfs configuration on the client, to restart nfs service on the synology. But nothing works. If I want to get back to my 100MB/s I have to reboot the VM, until the problem occurs again.

 

Does anyone would know what I should do ?

 

Thanks.

what is the brand of nic you are using? I've heard of similar problems to yours with some realtek nics, intel seem better.

They seems to be an intel. Here what I have from lspci :

 

06:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)

06:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)

ok so its probably not the nics then :smile:

Have you looked at the folder nfs settings and seeing if adjusting them makes a difference, eg setting async, setting host ip permissions rather than wild cards etc.

I have already played with the nfs settings, even reload the nfs service, but nothing worked.

But, I just noticed that my xpenology on my proxmox server was using realtek driver ! I've changed it to intel, and I'll see if it works better.

Well, it's seems it's working normally now. I don't have any drop performance for two days. The issue was that I choose the wrong network driver on my proxmox server for this vm.

Thanks for your help.
