        Koja je poenta ovoga? Zar su stvarno mislili da ce moci da sakriju podatke o brzini?

        Disable SMT/Hyperthreading in all Intel BIOSes

        Two recently disclosed hardware bugs affected Intel cpus:

        - TLBleed

        - T1TF (the name "Foreshadow" refers to 1 of 3 aspects of this
        bug, more aspects are surely on the way)

        Solving these bugs requires new cpu microcode, a coding workaround,
        *AND* the disabling of SMT / Hyperthreading.

        SMT is fundamentally broken because it shares resources between the two
        cpu instances and those shared resources lack security differentiators.
        Some of these side channel attacks aren't trivial, but we can expect
        most of them to eventually work and leak kernel or cross-VM memory in
        common usage circumstances, even such as javascript directly in a
        browser.

        There will be more hardware bugs and artifacts disclosed. Due to the
        way SMT interacts with speculative execution on Intel cpus, I expect SMT
        to exacerbate most of the future problems.
        VMware Performance Impact Statement for ‘L1 Terminal Fault - VMM’ (L1TF - VMM) mitigations: CVE-2018-3646 (55767)

        Our tests showed that after enabling the ESXi Side-Channel-Aware Scheduler the maximum performance capacity of the host can diminish by as much as 30%, depending on the workloads, host utilization, and processors used within the host. It is important to note that this does not necessarily translate to a 30% reduction in application performance. On a host that is running below its maximum performance capacity, the enablement of the ESXi Side-Channel-Aware Scheduler might result in little or no loss of performance depending on how much spare capacity was available. A set of test results for common enterprise application workloads is included in the Performance Test Results section of this article.
