Hey everyone, I bought an Intel X550-T1 on eBay and tested it only to find out it craps out at around ~326MB/s (2.6Gbit/s). Thinking it may be my Ethernet cable (50ft CAT5e), I swapped it for CAT6 but atlas that did not help. So I tried putting the card in a separate computer with a different CAT6 cable and that did nothing.
I also ran Iperf3 on my client computer and server which has a SolarFlare SF432 (dual 10Gbit SPF+) and I'm getting roughly the same speeds as before ~3.15Gbit/s. So what gives?
Server:
Intel Xeon E5-2683 v3
MSI Gaming X99A GODlike Gaming
64GB (4x16GB) DDR4 2133
110TB storage
Seasonic FOCUS Plus 750W
NAS4Free (latest build)
SolarFlare SF432
Client:
AMD Ryzen 7 2700X
ASUS Strix Gaming B350-F
16GB (2x8GB) DDR4 3200
HP 1TB EX920
GTX 1080Ti
EVGA 750 GQ
Windows 10 Professional x64 1803
Intel X550-T1
10Gbit switch: MS510TXPP (says both computers are getting 10G Full Duplex)
I also have another computer with a SolarFlare SF432 that I have directly connected to my server and it gets the full 10Gbit/s speeds.
