Dear all, recently the main branch was changed to build the TCP RACK stack which is a loadable kernel module, by default: https://cgit.FreeBSD.org/src/commit/?id=3a338c534154164504005beb00a3c6feb03756cc As discussed on the bi-weekly transport call, it would be great if people could test the RACK stack for their workload. Please report any problems to the net@ mailing list or open an issue in the bug tracker and drop me a note via email. This includes regressions in CPU usage, regressions in performance or any other unexpected change you observe. You can load the kernel module using kldload tcp_rack You can make the RACK stack the default stack using sysctl net.inet.tcp.functions_default=rack Based on the feedback we get, the default stack might be switched to the RACK stack. Please let me know if you have any questions. Best regards Michaelhome | help
