iperf3 results between Chelsio T6225-CR and Intel X710-DA4
I ran two iperf3 tests between two hosts using Chelsio T6225-CR and Intel X710-DA4, respectively. Both NICs are connected to the supervisor interfaces on a Sup8E in a Cisco Catalyst 4500E chassis. Wirespeed is 10 Gbit/s.

After upgrading this system to stable/12 r348672, my Chelsio T6225-CR NIC finally provided acceptable performance.

Somewhat improved iperf3 performance on Chelsio T6225-CR
After upgrading to stable/11, r339418, incorporating the recent commits for cxgbe(4) et al. (r339389, and r339393-r339404), I see a somewhat improved iperf3 performance.

I ran four tests yesterday using iperf3. The T6225-CR NIC still runs with Chelsio’s SM10G-SR optics. It’s amazing that receiving TCP streams runs at full speed. Sending TCP streams limps away only at a few megabits per second. This wasn’t expected at all. Even IPv6 runs faster than IPv4 for these particular tests. The Cisco […]

Chelsio T6225-CR and TOE
After upgrading to a recent base/stable/11, I noticed ifconfig -m now displays two more bits: TOE4 and TOE6 appear in the capabilities word, but not in the options word. (TOE in this case being TCP Offload Engine.)

I finally got my two Chelsio SM10G-SR SFP+ optical modules. First light have finally been achieved.

I recently ordered a Chelsio T6225-CR network interface card and a couple of SM25G-SR SFP28 optical modules. The aim is to get a 10 Gbit/s connection to the LAN, utilise the off-load capabilities of the NIC, and of course utilise the on-board crypto accelerator. The latter will not be useable until the system moves to the upcoming […]
