I wouldn't expect such a substantial difference, though. It's also interesting that Epyc reports AES-XTS support while Xeon does not= .=20 That suggests the Xeon is running a different (older) version of FreeBSD th= an the Eypc. Maybe that's just from installing CURRENT on the Epyc, but for apples-to-apples comparison I'd suggest running the same version. When you installed CURRENT, did you compile a GENERIC-NODEBUG kernel / defi= ne MALLOC_PRODUCTION for world? Or is this just a snapshot published on the freebsd ftp server? If the latter, it's a debugging-enabled kernel, which = will result in substantially higher sys time. --=20 You are receiving this mail because: You are the assignee for the bug.=
