The boot memory test is disabled by default, as it takes a significant amount of time on large-memory systems, and is unfriendly to virtual machines as it unnecessarily touches all pages. memtest = 0; TUNABLE_ULONG_FETCH("hw.memtest.tests", &memtest);
это в десятке уже так. в девятке, тем временем:
By default enable the memory test on real hardware, and disable it if we appear to be running in a VM. This avoids touching all pages unnecessarily, which doesn't matter on real hardware but is bad for shared VM hosts. Use a general name so that one could eventually do more with the code than just disable it. memtest = (vm_guest > VM_GUEST_NO) ? 0 : 1; TUNABLE_ULONG_FETCH("hw.memtest.tests", &memtest);
