Adventures in NetBSD/amd64 10.0
When the harddrives in the oldest virtualization server at $WORK died, I was virtually left without any test systems running the other BSDs and some select Linux distros. We have another virtualization server with plenty of resources, and I decided to try NetBSD/amd64 10.0-RELEASE, build a few packages, and upgrade the VM to 10.0-STABLE.

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 […]
