https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D265714 Nick Koss <nkoss1992@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |nkoss1992@gmail.com --- Comment #25 from Nick Koss <nkoss1992@gmail.com> --- Hey Folks - Just wanted to cast my stone into the pond regarding this issue. I'm running OPNsense on FreeBSD 14.2. I have an HP Flex IO i225 NIC install= ed in my HP Elitedesk 800 G6 Mini. Current firmware version is 1.57. I am unab= le to upgrade the nvm via nvmupdatemanager64 since the firmware is HP propriet= ary, with 1.57 being the highest available version from HP. I run the NIC at 2.5 Gbe. Under load, my speeds will drop down to around 500-600 Mb/s with large amounts of retries in iperf3. I can induce the speed drop by rapidly starting/stopping iperf transfers. I've tried everything - tunables, BIOS power settings/ASPM, AIM settings, E= EE settings. Nothing has remedied the issue. I have an identical PC with the same NIC installed, which runs Linux (Proxm= ox). The NIC in this machine does not experience any drops. This leads me to bel= ieve that the Linux drivers are able to compensate for any NIC hardware/microcode issues. The firmware of the NIC in the Linux box is also 1.57. My pciconf output: class=3D0x020000 rev=3D0x03 hdr=3D0x00 vendor=3D0x8086 device=3D0x15f3 subv= endor=3D0x103c subdevice=3D0x87b9 Hopefully as time goes on there may be a takeaway from the Linux driver that FreeBSD implements. My feeling is that most folks experiencing issues with = this NIC have variants that are not OEM Intel. --=20 You are receiving this mail because: You are the assignee for the bug.=
