I think I found the kernel which adds the first downgrade in performance between 6.5.0-45 and 6.8.0-38. I tried the same downloads with kernels on mainline repo:
6.7.6-060706-generic = 2025-04-22 20:17:13 (323 MB/s) 6.7.7-060707-generic = 2025-04-22 20:37:24 (229 MB/s) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2107347 Title: Severe Network Performance Regression with BCM57800/BCM57810 on Kernel 6.8.0-40 through 6.12.16 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2107347/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
