two sockets. not sure how this impotant, just for record. you system also w/o INVPCID feature (as kib question). may be you case also will be resolved by vm.pmap.pcid_enabled=0? > CPU: Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz (2700.06-MHz K8-class CPU) > Origin="GenuineIntel" Id=0x306e4 Family=0x6 Model=0x3e Stepping=4 > > Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> > > Features2=0x7fbee3ff<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,PCID,DCA,SSE4.1,SSE4.2,x2APIC,POPCNT,TSCDLT,AESNI,XSAVE,OSXSAVE,AVX,F16C,RDRAND> > AMD Features=0x2c100800<SYSCALL,NX,Page1GB,RDTSCP,LM> > AMD Features2=0x1<LAHF> > Structured Extended Features=0x281<FSGSBASE,SMEP,ERMS> > XSAVE Features=0x1<XSAVEOPT> > VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID,VID,PostIntr > TSC: P-state invariant, performance statistics > real memory = 274877906944 (262144 MB) > avail memory = 267146330112 (254770 MB) > > 12 cores x 2 SMT x 1 socket > > Warner _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
