Network performance dropping below expected rates on a 10gb connection
Network performance dropping below expected rates on a 10gb connection
Checked for any missed details. Card copies at 275MB/s to server but slower over ASUS 100C with high latency. Switch shows 10GB uplink, Windows shows 10Gb negotiation. Possible causes could be driver issues, network congestion, or cable quality.
It's my desktop with an ASUS 100c networking card. That goes over cat6e to the SFP Plus, that slots into my switch which supports 100 meg or 10 gig on that port. Then that goes out 2.5 gig to my NAS. I am still waiting on the fiber interconnect from the NAS to another 10 gig SFP+ port on my switch. My on-board 2.5 gig from the desktop to the 2.5 gig port on the switch operates much faster than my 10 gig to the 10 gig port on the switch. I've heard bad reviews of this ASUS card I have so I'm suspecting maybe that's a problem but I don't know. I ordered another Intel 10 gig card, and I'm going to make another cable here later today and see if that changes anything
Yes, you can set flow control through the switch using the switch's configuration. If it doesn't function properly on your port, adjust it on the NAS port as well. On my first setup, I faced performance drops for Gigabit clients connecting to a 10Gbit NAS without proper flow control settings.
I can enable flow control and see what happens. The SFP+ supports up to 100 megabits or 10 gigabits. There’s no direct single-mode fiber connection to Nas once switched, so no copper will be used in the line.
