No avail. I'm o a Dell R730xd E5-2699 v4, running Ubuntu Jammy on the baremetal, no virtualization.
On any kernel from 5.15 up to 6.5.0-45 I reach 350MB/s in a wget from one internal server, then on kernel 6.8.0-38 and 6.8.0-39 I see a drop to 260MB/s and from 6.8.0-40 onwards it drops again to 30MB/s, testing against external servers (wget https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.14.1.tar.xz) I see 45MB/s -> 20MB/s -> 500KB/s This happens on all machines we tested with BCM57800/BCM57810 nics (bnx2x module). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2098961 Title: Severe network performance issues with Kernel 6.8.0-53 and 6.11.0-17 (Xubuntu) on Proxmox 8.3 (bnxt_en + VirtIO) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2098961/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
