Hallo zusammen,
bin bei uns für die Hardware in der Konstruktion zuständig, und verfolge im I-Net die Meldungen zu dem Meltdown und Spectre Problem. Hat da jemand schon Erfahrungen sammeln können? Bei den Meldungen ist ja alles dabei, von "20% - 50% Leistungseinbußen" bis "gar keine Auswirkung" und kann den PC nicht mehr nutzen.
Meltdown
Bei bei I/O-intensiven Anwendungen muß man wohl mit einem hohem Performance-Verlust rechnen.
Interessant ist hier das Win7/Win8 User Performance-Verluste hinnehmen müssen, Win10 User auf neuer Hardware eher nicht. Ein Schelm wer böses Denkt

Zitat:
PerformanceOne of the questions for all these fixes is the impact they could have on the performance of both PCs and servers. It is important to note that many of the benchmarks published so far do not include both OS and silicon updates. We’re performing our own sets of benchmarks and will publish them when complete, but I also want to note that we are simultaneously working on further refining our work to tune performance. In general, our experience is that Variant 1 and Variant 3 mitigations have minimal performance impact, while Variant 2 remediation, including OS and microcode, has a performance impact.
Here is the summary of what we have found so far:
With Windows 10 on newer silicon (2016-era PCs with Skylake, Kabylake or newer CPU), benchmarks show single-digit slowdowns, but we don’t expect most users to notice a change because these percentages are reflected in milliseconds.
With Windows 10 on older silicon (2015-era PCs with Haswell or older CPU), some benchmarks show more significant slowdowns, and we expect that some users will notice a decrease in system performance.
With Windows 8 and Windows 7 on older silicon (2015-era PCs with Haswell or older CPU), we expect most users to notice a decrease in system performance.
Windows Server on any silicon, especially in any IO-intensive application, shows a more significant performance impact when you enable the mitigations to isolate untrusted code within a Windows Server instance. This is why you want to be careful to evaluate the risk of untrusted code for each Windows Server instance, and balance the security versus performance tradeoff for your environment.
Ich hoffe mal das der Patch nicht unsere Workstations lahmlegt....
