I have 2 unraid servers, just upgraded to a 10gbe/2.5gbe switch, which is fed by a DAC to the switch from my UDM:SE
(Version: 6.10.0-rc2) AMD 3900x - 2.5gbe card (cat6 to the server 2.5gbe port)
(Version: 6.10.0-rc2) Dell r630 with E5-2620 v3 x2 - Intel x540 10gbe card (server rj45 10gbe to sfp+ to eth cat6 in the switch)
Each server has a VM and all updated windows 10, on the AMD server I can max out my internet 1.4gb down on a speedtest, the Dell server I cant seem to get over 1gbe, unraid says its connected at 10gbe on the Dell. I know the dell is older equipment but, why the slowness.
I took a 6gb iso from my laptop which is hooked up 2.5gbe to the same switch, I was able to write to the AMD server at 280 MB/s (maxing out my nvme). I did the same test with my Dell which as a 2.5 SSD, i know its not as fast as the nvme, but I can only get 80 MB/s on the transfer.
Something is bottlenecking the Dell and I cant tell when it is. Any Ideas on why slow on the Dell Server?
