https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D242747 John Baldwin <jhb@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |asomers@FreeBSD.org --- Comment #27 from John Baldwin <jhb@FreeBSD.org> --- (In reply to Eirik Oeverby from comment #26) This means that the Epyc box is in fact using the "hardware" (well, acceler= ated software) instructions like the Xeon, so your issue is not that it is doing "plain" software encryption. I would suggest perhaps using hwpmc to investigate where the CPUs are spending time, but the title of this bug is rather stale at this point. Investigating the poorer performance on Epyc m= ight be worth doing in a new PR. Alan Somers has done some performance work with geli in current and might have some ideas on areas to investigate. --=20 You are receiving this mail because: You are the assignee for the bug.=
