Avail memory is the total memory as reported by EFI map. Damn - thank you very much. That was the answer. I was under the impression that the machine has 1.5T installed, but in fact it has only 1T installed. I was expecting holes because of NUMA, but my assumption was more that the holes would led to memory being outside of the direct map space. > > Verify all that by looking at sysctl machdep.efi_map output. > > > > On Fri, Mar 22, 2024 at 07:54:06PM +0100, Bernd Walter wrote: > > > .. > > > real memory = 1649265344512 (1572862 MB) > > > avail memory = 1057138888704 (1008166 MB) > > > .. > > > > > > I suspect address space issues, but don't know for sure. > > > Changing NUMA nodes per socket in the BIOS had an influence to make it > > > worse, but not better. > > > > > > > > > Copyright (c) 1992-2021 The FreeBSD Project. > > > Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 > > > The Regents of the University of California.
