    Phoronix: The Networking Changes For Linux 5.17 Are Very Exciting

    The Linux networking subsystem updates for the in-development 5.17 kernel are quite exciting as usual given how prolific Linux is from large servers in the cloud to running on enterprise networking gear down to Linux on small IoT hardware. Not only is there a lot of hardware driver action as usual but also some key performance/latency optimizations...

    Well then I guess I'm excited. But only mildly, since I'm not running servers myself.

      If only it would not take years before we see enterprise Linux distributions are released with a new enough kernel. Unless this is back-ported by the Enterprise OS vendors, this will not get to most server customers until RHEL10 (as RHEL9 is already in beta and using an older kernel).

        When you believe your business needs these improvements today, but you solely rely on distros to provide you, then you are doing something wrong.

          Yes we could use this as we have 100GbE in production (and various improvements for Rome CPUs found in recent kernels). And we are perfectly capable of building our own kernels. But in the end the business demands a supported environment by hardware and software vendors, so compiling our own kernels is not an option.

          In addition, even if RHEL9 were to come out tomorrow, it would likely still take around a year for HW and SW vendors to catch up and support it. At least that was the case with previous major version bumps.

            mptcp in the wild would be cool

              Then you do not need it.

                Yes oracle. So insightful, such brilliant answers.

                  You want things you know you cannot have. So you complain. Your problem is right there.
