grotoc311 Posted August 15, 2017 Share #1 Posted August 15, 2017 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.

sbv3000 Posted August 17, 2017 Share #2 Posted August 17, 2017 what is the brand of nic you are using? I've heard of similar problems to yours with some realtek nics, intel seem better. Quote Link to comment Share on other sites More sharing options...
grotoc311 Posted August 17, 2017 Author Share #3 Posted August 17, 2017 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) Quote Link to comment Share on other sites More sharing options...
sbv3000 Posted August 17, 2017 Share #4 Posted August 17, 2017 ok so its probably not the nics then 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. Quote Link to comment Share on other sites More sharing options...
grotoc311 Posted August 17, 2017 Author Share #5 Posted August 17, 2017 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.

grotoc311 Posted August 19, 2017 Author Share #6 Posted August 19, 2017 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. Quote Link to comment Share on other sites More sharing options...
