Transmission rates are significantly lower compared to incoming data rates.
Transmission rates are significantly lower compared to incoming data rates.
I set up a new Windows Server 2019 Tyan 1U machine with a 10Gb NIC using an SFP+ connector. The setup includes a switch for connecting the server and other gear. The server connects via an SFP+ to SFP+ cable showing a 10Gb link, while RJ45 ports show a 2.5Gb connection. Data moves at about 280MB/s to the server and 50MB/s from it. I’ve tested using an SFP+ to Ethernet transceiver inside the server port and then through a CAT7 cable to the switch, but speeds remained unchanged.
I'm sending data from the server. Check if its storage or the service can handle higher speeds using iperf3 for testing.
Consider your topic formatting carefully to avoid confusion. Are you referring to 280 M B per second and 2.5 G bps? Do you mean 50 Mbps or 50 MB/s in the opposite direction? What data are you moving—small files or large ones? Also, what are the disk specifications and protocols involved? These aspects might actually be limiting performance instead of the connection itself.
Surprised, but the post was made too soon in the morning. Updated. Confirmed 280MB/s download and 50MB/s upload. Moving a 200GB file as a test. Performance matches what Explorer shows and the transfer time is recorded. Also checked with a 300MB test using LANSpeedTest.
Extremely large video files are present (200GB). I also rely on LANSpeedTest to evaluate connection performance. The storage needs to support read speeds exceeding 400MB/s. After noticing the problem, all subsequent tests will be conducted on an internal boot SSD with read and write capabilities surpassing 500MB/s. Every client is utilizing NVMe drives that offer significantly faster speeds.
I’m noticing signs that the new NIC might be underperforming compared to the previous setup. I’m transitioning from a 1Gbps connection where both input and output were about 112MBps, which seems normal. The same storage media is being used now, but the performance feels off.
